Magnavox Amplifier | USA

In 1910 Magnavox started as “Commercial Wireless & Development Company” at Napa, California. Peter L. Jansen, Edwin S. Pridham (both ex Federal Telegraph Company) and Richard O’Connor (finance) formed the company to achieve a sensitive telephone receiver. In 1915 Jensen and Pridham have put a horn to their “telephone receiver with moving-coil system” and then used it as a “Fog-Horn” for the local baseball park (Radio & TV News, February 1959). They called it Magna Vox. They developed a phonograph pickup and made a joint venture with Sonora in 1917 called “Commercial Wireless & Development Company”. They developed the “SE4005 noise-cancelling microphone” for aircraft intercoms. In 1919 Magnavox moved from 526 Mission Street, San Francisco to 14th Street in Oakland and made vacuum-tube power amplifiers. In February 1920 Magnavox introduced a radio speaker, forerunner of the 1921 Model R-3. 1924 Magnavox began also to produce a tube “A” with a special design and a year later also radios.

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).

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.

Magnavox 8802 tube amplifier recently pulled from working, mint condition console. I cleaned it up, removed the molex connector and bridged the power circuit to bypass the power switch in the separate preamp but other than that the unit is as it was in the console. This amp works great as is but for stand alone use the 390k resistor modification is recommended to bypass the balance pot on the separate preamp this amp used inside the console.
