For model TPA-1 M32, Philco, Philadelphia Stg. Batt. Co.; USA:
The Philco model TPA-1 All-Transistor portable 45rpm phonograph that I have just acquired, is in "Like New" condition. The phonograph's wood cabinet (9" x 8" x 6.5"), is covered with a dark green leatherette material and has a leather carrying strap on top. The Philco model TPA-1 played only 45rpm records and used (4) 1.5v "D" batteries for its power supply. And the phonograph tone arm contained and uses a monaural Astatic crystal pickup cartridge with a "K" 1 mil. diamond or sapphire stylus needle (Philco Part #325-8001 cartridge assembly). This Astatic crystal cartridge needle assembly, delivers a 3.0v voltage output and uses a 10 gram tracking force for the phonograph tone arm. Philco had first announced its "NEW" consumer product using transistors in the Summer of 1955 and started selling it to the market in the fall of 1955 ($59.95). This 1955 Philco consumer product, was the World's FIRST All-Transistor phonograph to be developed and produced.

Notes

The TPA-1 stands for "Transistor Phonograph Amplifier". The "Philco Service Supervisor" of October 1955 features the TPA-1 and TPA-2. TPA-1 and TPA-2 are transistor amplifiers with push-pull class B output stage. Wooden with cloth covering.

This Philco TPA-1 All-Transistor 45rpm battery operated portable phonograph is NOT a record changer. It can only play one 45rpm record at a time. You have to manually place a  45 rpm record onto the phonograph platter and manually move the tone arm onto the 45rpm record to play it. And when 45rpm record is finished, you have to manually pick up the tone arm and place it back onto the phonographs's arm rest.

The 1955 Philco's Models TPA-1 (M32) and TPA-2( M32A) All-Transistor 45rpm portable battery operated phonographs was the World's First All-Transistor phonographs to be developed and produced.

Hi everyone,

I have been searching to acquire a 1955 Philco model TPA-1 All-Transistor portable 45rpm phonograph for over 10 years. And I just recently had finally acquired this "Rare" Philco item, which was one of Philco's FIRST consumer products to use transistors instead of vacuum tubes. Philco had first announced its "NEW" consumer product using transistors in the Summer of 1955 and started selling it to the market in the fall of 1955 ($59.95), for Philco's 1956 season of its new line of radios and phonographs.

This 1955 Philco consumer product, was the World's FIRST All-Transistor phonograph to be developed and produced. After the 1956 season had ended, Philco had decided to discontinue the All-Transistor portable 45rpm phonograph models, for transistors were too expensive compared to vacuum tubes. Philco's All-Transistor portable 45rpm phonographs came in (2) models, which were TPA-1(M-32) and TPA-2(M-32A). The "TPA" stands for "Transistor Phonograph Amplifier" and its circuitry used (3) Philco Germanium PNP alloy-junction transistors (NO Vacuum Tubes).

These Philco All-Transistor phonograph models played only 45rpm records and used (4) 1.5v "D" batteries for its power supply. And the phonograph tone arm contained and uses a monaural Astatic crystal pickup cartridge with a "K" 1 mil. diamond or sapphire stylus needle (Philco Part #325-8001 cartridge assembly). This Astatic crystal cartridge needle assembly, delivers a 3.0v voltage output and uses a 10 gram tracking force for the phonograph tone arm.

The Philco model TPA-1 All-Transistor portable 45rpm phonograph that I have just acquired, is in "Like New" condition. The phonograph's wood cabinet (9" x 8" x 6.5"), is covered with a dark green leatherette material and has a leather carrying strap on top. The circuitry is 100% original, with its (3) Philco transistors (L-5021, L-5022) all having date codes of (5542), which is the 42nd week of 1955. And underneath the record platter is another printed date code (541), which is the 41st week of 1955. The inside transistor circuitry drives a 4" permanent magnet dynamic speaker, inside the front of the wood cabinet, which gives this unit good sound acoustics and volume.

And best of all.... It still contains the original Astatic crystal cartridge with Astatic "K" red 1 mil. diamond stylus needle and this unit still works "Great". I have made a short film clip of it and plan to put it on YouTube. When I am finished, I will update and add this video clip link to this site for all to see.

Finally, if anyone has either of these Philco models TPA-1 and TPA-2, please contact me thru my PM (private mail).

Thanks Rick

I am wondering if anyone has the 1956 Philco Factory Supervised Service Home radio Yearbook, for I need the service information and schematic for the Philco TPA-1 phonograph, which is listed in this particular book ??

Also, does anyone have this Philco TPA-1 phonograph unit in their collection, for I would like to see an actual picture of it.

Thanks Rick (rickhirsh[A*T]yahoo.com)

Hi Rick,

I have the Philco 1956 Home Radio Yearbook, and have scanned and uploaded three pages which you can now view and download.

There is a fourth page, but it is merely the same schematic as one of those already available.  The fourth page includes a parts list, but it doesn't really have much information not shown directly on the schematic, so I didn't upload it.

Best regards,

Tom

Hi Thomas,

 

"THANK-YOU" very much for uploading the service info from the 1956 Philco Factory Service Home Radio Yearbook. I would also greatly appreciate it if you would take the time to also upload the fourth and final page of this book manual to this site. Thanks Again for all your help !

Finally, has anyone have either the TPA-1 or TPA-2 in their collection and if yes, could you take a picture of it and upload it to this site ?

Thanks Rick
