Help identifying a philco model - elfiself - 03-12-2018

Looks like a 42-PT7 but with 6 tubes instead of 5. Purchased as a 42-PT3 which is identified at radio museum as a 5 tube wooden cabinet with the same tube lineup as the PT7. Sticker on rear of chassis # T47958. Paper tag inside cabinet Part No. 10592-c is I think a cabinet designation. Tube lineup of this radio is 50L6GT, 7C7, 7B7, 35Z3, and 7A8 (maybe).
Nostalgia Air doesn't list a schematic for a 42-PT3. Not sure what I have here.

Odd,
The Philco gallery shows it but no tube count. Radiomuseum shows 5 tubes too.

Methinks you got  http://www.nostalgiaair.org/pagesbymodel/123/M0014123.pdf
OBTW the tube by the tuning cap is a 7C7 not a 7C6.

RE: Help identifying a philco model - elfiself - 03-12-2018

I found the 46-420, 421 ect. which seem similar but tuning dial is different and they use a 35Z5 not the 35Z3.

RE: Help identifying a philco model - Radioroslyn - 03-12-2018

Sorry misread your post and thought you were looking for a diagram for the 6 tube set. There's a bunch of 5 tube models.

Next time, try here first.

Now. You say your chassis has six tubes yet you only list five?

Quote:Tube lineup of this radio is 50L6GT, 7C7, 7B7, 35Z3, and 7A8 (maybe).

That's five tubes.

The 42-PT2, 42-PT3, and 42-PT7 uses these five tubes: 7A8, 7B7, 7C6, 35Z3, 50L6GT.

Model 42-PT10 uses six tubes: 7C7, 7A8, 7B7, 7C6, 50L6GT, 35Z3.

Please confirm whether you have five or six tubes.

If five, it is OK. If six, then you have a 42-PT7 with a 42-PT10 chassis, which means that someone in the past took two radios and made one. Maybe they had a 42-PT10 and broke the (Bakelite) cabinet, liked the RF amp which the 42-PT10 has, so stuck the chassis in a 42-PT7 cabinet?

Terry i am looking for a 6 tube set
50L6GT, 7B7, 7C7, 7C6, 35Z3, 7A8
PT12 has right tube lineup
Guy I bought it from thought he was selling me a 42-PT3 which is what I wanted because the PT3 has the same schematic as the PT7. However, he doesn't think the cabinet looks like a pt12. Could be a PT12 chassis in a PT3 cabinet.
This radio has an RF transformer like the PT12 .

It would be greatly helpful if you would post pictures of the radio in question. Then there would be no doubt as to the cabinet.

I believe that I have already identified the chassis in post #6 above. Icon_rolleyes While it could also be a PT-12 chassis, I would have to look up the schematic to see if the tube lineup matches between PT-12 and 42-PT10.

RE: Help identifying a philco model - elfiself - 03-13-2018

Ron I looked at the 42-PT10 and it didn't click. I think you're right on; thanks elfiself

RE: Help identifying a philco model - elfiself - 03-14-2018

Question on radio continues.  Seems most 42-PT12 have plastic case.  The model I have has a wood cabinet I feel is original as the aerial loop is mounted on a paper strip which was stapled on the back interior of the cabinet.  Please see attachments.  I removed the chassis w/aerial cabinet is very rough and in pieces.

as a side note 42-PT -10 schematic shows 2 7C6 tubes, PT12 schematic shows 1 7C6 and 1 7C7. This radio has 1 7C6 and 1 7C7

RE: Help identifying a philco model - elfiself - 03-14-2018

Just noticed on Riders page 12-44 Philco PT12 schematic shows 1 7C6 and 1 7C7. Diagram of top of chassis shows 2 7C7.

> Seems most 42-PT12 have plastic case.

All true, factory original 42-PT12 sets have Bakelite cabinets.

> PT12 schematic shows 1 7C6 and 1 7C7. This radio has 1 7C6 and 1 7C7

Well, there you go. It's a PT-12 chassis in a 42-PT3 cabinet. That is a (badly discolored) 42-PT3 cabinet.

> Diagram of top of chassis shows 2 7C7.

What diagram?
