Luxman MQ60 Custom Stereo Tube Power Amplifier. Came out in 1974, this is a true classic tube amplifier. I’m not a technician at these, but it appears to be working fine as I tested with my audio. Please note this is just a basic test that the unit was producing sound through Input, and the volume knobs working well to the best of my knowledge. It’s sounding great! Cosmetically the unit is in nice condition as you can see. There are some minor marks and wear here and there, a bit of chip on the knobs on the back as shown, but nothing major. I’m including plenty of pictures so you can see exactly how it looks. Please refer to my pictures for any details. Sold as is.

Knight Catalog 1964

The company was started by Simon “Sy” Wexler in 1928. Allied Radio was an American radio manufacturer and retailer, which sold radio sets, tubes, capacitors (also known as electronic components), amateur radio equipment, citizen’s band (CB) radios, miscellaneous communications equipment, electronic kits, and consumer audio systems through retail stores and mail-order.

In 1962, The first industrial catalog was released for its commercial supplier division under the name of Allied Electronics. Through the 1960s both divisions would be headquartered in Chicago. Allied Radio would change ownership in 1970 when Radio Shack’s parent company (Tandy Corporation) bought both Allied Radio & Allied Electronics. In 1999 the company was acquired by Electrocomponents, the largest catalog distributor in the world.

Here’s a magnificent 1921 Magnavox AC-2 amplifier. The amp is original, it’s working, it’s in excellent condition (still has its original Magnavox hang tag and cabinet label), and it comes a good pair of early, tipped amber glass UV-201 tubes. The tubes have been tested in the amplifier, and they still work. The AC-2 was designed to be used with either radio or PA input, with B+ plate voltages running as high as 90v. It can be used with almost any 1920’s battery radio or crystal set and can be powered by either dry cell batteries or a regulated DC power supply (such as an ARBEIII).

Detail
Detail

As you can see in the photos, the condition of this amplifier is excellent throughout. The panel is beautiful and undamaged, with legible engraved lettering and original nickel plating on the control assembly that still gleams. Cabinet is likewise in excellent condition, with an original finish that’s still as smooth as satin and an original full-color Magnavox decal that’s almost perfect. Chassis is clean and correct and original, and the huge original Magnavox AF transformer is still good. The 1st stage rheostat is open on a single turn at the very beginning of its travel, but this has no effect on the functionality of the amp, as the rheostat is in the off position when the stator is at that setting anyhow. Both rheostats gradually raise and lower the voltage, as they should, and both amplifier stages work properly, as you toggle each one off and then on. A few of the binding post nuts have worn threads, but they can still tighten down on battery wires.

The Magnavox license on the underside of the base is original and the original hang tag is in excellent condition. If you want to operate the amp, you’ll need a regulated DC power supply or high current, low voltage dry cells for the tube filaments (1 amp) and high voltage, low current batteries for the tube plates. Please note: this is not an AC amplifier. You do don’t simply plug it into a wall outlet. Also, it must be impedance matched to both input and output devices, and it was designed to be used with early 1920’s radio and public address devices, not 1950’s audio gear. Please know what you’re bidding on. Depending on what type of input device you’re using, and how that device is grounded, a separate, dedicated DC power supply may be required for the amp.

Tested: Works well with the usual crackle in the pots and switches, especially the Balance control. A good inside cleaning should be done before using. It sounds great. All ins have been tested and they work properly. Both Moving Coil and Moving Magnet Phono stage settings work. All four speaker outs work. Tone controls all work. Output LEDs work. Power indicator works. Cosmetically the unit is in very good condition. I tried to include flaws in pictures. Could use a detailed cleaning. The numbering and lettering on faceplate is intact. Some other tiny flaws from age may be present, but nothing worth noting.

Please see the video on You Tube http://youtu.be/29k-E53pAOc for more details and ask any questions. According to the Blue Book this 20 Watt Mono Tube Amplifier was produced in 1977-1979 and it cost $185.00 new. If you take inflation into consideration this amp would cost over $700.00 today as compared to 1977. Also according to Blue Book this is “Very Rare”, but when you consider it is new in the box it would be considered extremely rare and maybe even one of a kind. It all works and sounds great and is perfect except for the bass pot is reversed but works as it should. Minimum is the max and vice versa. This is all shown in the video. The 6V4 tube is an Amprex Bugle Boy made in France, the two 6bq5s are RCA as are the two 6EU7s.

MARANTZ 9 Reissue Tube S/N 10040 ,10050. Used, 100% all functions operate. External aesthetic conditions are excellent. These power amps work at 230v. Anyway please take note that: The reissue amps have many primary transformer taps to match voltages of 100V (Japan), 120 Volts USA, and 220V and 240V. The originals can not do this but the reissues have the taps to rewire.

Detail

Many times they are cut short under the circuit board but can be spliced and connected. Original user guides, the two power cords and the original boxes are included. Few light scrathes are present on the black covers of the transformers. In the front alluminium covers only two points have a scartch (please look the red arrows). On request I ll be glad to send you more detailed photos. Made in USA by VAC.

Tubes installed in the two mono tube amps are :

  • 4 E88CC Philips SQ
  • 2 6CG7 General Electric
  • 8 6CA7/EL34 (I suppose Electro Harmonix or Gold Lion)

Rare and superb sounding 70 watt Stromberg Carlson SAU-70 dual 6550 Tube amplifier. All the tubes are working and included (I don’t have any 6550’s so I included two 6L6GC tubes instead)…..

Detail

2) 6L6GC (subs for the 6550 tubes)
1) 5Y3
1) 5U4
2) 12AX7
1) 6U8

The front panel has separate volume control knobs for MIC-1, MIC-2 and Phono plus a Bass/Treble/On/Off control. The back panel features a Speaker output socket plus a 1/4″ speaker output with a wire that allows you to choose 4, 8, or 16 ohms speakers. There is an RCA plug for Radio/Phono/CD Input, a 1/2″ MIC input and a 1/4″ guitar plug. There is also a Hum Adjustment on the top of the chassis.

Detail

We tested this amp with a microphone, CD player and a guitar using an 8 ohm speaker. Everything on this amp works perfectly and it sounds wonderful! It’s very loud (rattles the windows) with a great vintage tone and no background hum or hiss what-so-ever! All the transformers and capacitors stayed nice and cool during our testing and all the knobs turn freely and quietly. The chassis does have some minor surface rust but the cage is in great shape as you can clearly see in the pictures. The power cord was taped by someone else and I believe the amp is all original except for the 1/4″ input and speaker sockets. It measures approximately 16 1/2″ x 9″ x 7 1/4″ and weighs about 29 lbs. unpacked.

Detail

All tube amplifiers are brought up to full power slowly with a variac to avoid damage and to reform the capacitors. Although I test them to the best of my ability, I am not an expert! When purchasing vintage items you should expect that some may need work and remember that the warranty ran out on our items decades ago! By bidding on my auctions.

This is a very nice Harman Kardon A30K amplifier, serial number 6041830. The 30K is the kit version of the A300 amplifier. Electrically the 30K and 300 are identical. I never put power to these amps without first replacing the electrolytic and coupling capacitors and diodes. It is strongly recommended (Google ‘recapping radios’) that the electrolytic and coupling capacitors be replaced in old tube units. For the A300 there are a total of seven electrolytic capacitor sections in the power supply and a total of eight coupling capacitors to be replaced, which I have done. After restoration I also verified the B+ voltages and critical components are to specification. I also replace the rectifying diodes with more modern units that have fast turnoff/soft recovery, characteristics that provide a little less noise– makes for a cleaner power supply. No change in the sound of the amp, only just a cleaner power supply.

Detail

These restorations do not modify the wonderful ‘tube sound’–no real modifications, but rather put back the way the HK engineers designed it, only make the unit safer and more reliable. See pictures, showing new components and before and after chassis refurb. (bottom cover removed for picture).

In addition to replacing the electrolytic and coupling capacitors, using premium 716 Series Sprague Orange Drops for the coupling capacitors, I have tested all the tubes on my B&K 707 tube tester—and replaced any that were marginal. I also have cleaned the tubes, tube sockets, controls and switches (Deoxit D5 contact cleaner for the tube sockets and switches, F5 Fader Lube for the potentiometers). The output tubes are performance matched Sylvania 7408’s with identical date codes of 1962, 26th week. The 7408 is a more rugged version of the 6V6, which are highly prized in tube amplifiers. For tube rollers, the 6V6 is a direct replacement for the 7408.

Detail

I have verified all the operations. The controls and switches all function as designed. All the inputs are operational. I have run this unit 8 hours without any issues after the refurbishing. This unit has a very nice appearance, the faceplate is excellent for it’s age, the issue is a scratch on the upper LH corner, see pic. The vertical lines on the faceplate are from the lighting. This is one of the best A30K’s that I’ve had. The knobs also are in very good condition. Chassis has a few stains, chassis lettering is sharp and legible–see pictures. As a stereo integrated amplifier, there are inputs for lo level (magnetic) phono or tape head, hi level (ceramic) phono, tuner and auxiliary inputs. The controls are: Source Selector, Loudness (Volume), Bass, Treble, Balance, and Blend. Switches are provided for power, rumble filter, contour, equalization and stereo reverse

While it has not been tested, as you can see from trhe pictures it is extremely clean-almost looks to be new, but the frayed cord attestes it must have been in use at some time. Still exceptional cosmetics for a vintage amp.
Rated at 18 watts.

Detail

Amp is 14″ X 7″ X 8 1/8″tall. Weighs about 15 1/4 pounds.

The amp deck will be shipped via Fedex Ground within the United States. Ebay’s rate master does not support Fedex rates, so what you are seeing is UPS Ground rates. I strongly urge you to wait for an invoice after the auction ends before paying, as Fedex is usually less than UPS and I will bill you the lower amount for S&H.

All of the knobs work and turn freely as they should but the output of this one is very faint. So it will need some work or possibly new tubes to bring it back up to its full potential.

Detail

It looks like all the components underneath are still original and the chassis and cage are in good cosmetic condition as well (please see photos). So this one is a great candidate for a rebuild (I’ve heard one of these in good working order and they are VERY nice sounding amplifiers! It measures approximately 8″ x 5 3/8″ x 5″ and weighs about 8 lbs. unpacked.

Extraordinary opportunity!! 1 ea. (single) original 1960’s NOS, New in original box Telefunken EMM 801 double bar tuning indicator tube. This tube is SEALED IN ITS ORIGINAL PLASTIC!!!! You will be the first to open it. This tube has not seen the light of day in over 40 years. I recently purchased a whole sleeve of these tubes from a man who stocked up on them back in the 1960’s and never used them. You will get 1 (single) tube with this listing. 1 of the tubes in the sleeve was opened and I am going to keep that one (see photo), you will get 1 (one) of the sealed tubes.

This listing is NOT for the whole sleeve, only one tube, just to be clear. 4 of these are available at $99 each. You can put this sealed EMM 801 tube in your collection or you can open it and put it in your Dynaco or McIntosh MR67 tuner. These were also used in many recording devices. Telefunken stopped making these in the 1970’s and there is no equivalent or substitute tube for the EMM 801. These may be the only new, sealed Telefunken EMM 801 tubes left on the planet. All sales final, No returns on unopened tubes, sorry. I know there are people out there who would love to put their bad tube back in the box and return it for a full refund. Buy without worry, Check my feedback and bid with confidence. Buy it now on eBay!
