Philco 46-200 issues - Keng - 04-09-2022

Hello;

Our youngest son just presented me with an almost pristine Philco model 46-200 radio which he is asking me to get operational. There are no following numbers, i.e. 121, or etc. after the model number. The only other number printed on the chassis is 07c36203. There are 7A8, 7B7, and 7C6 loctals, and 35Z5 and 50L6 octals. There appears to be no 80 ohm resistor in the filiament string, and the radio has a PM speaker in it. From the above, I would assume it is either a -121 or perhaps a -125 model.

The only schematic I have so far been able to find is for what I assume is for an earlier model with the 14A7 and 14B6 loctals, the 35Y4 rectifier, and the PM speaker.

There is also a strange capacitor in it with several turns of what looks like black enameled formvar wire wrapped around one end. The radio has also been worked on some time in the distant past.

The bakelite case is in perfect condition, as are the knobs. The cardboard back is still in good condition.

At the moment, after turn-on, it is obvious that all the tubes are correct since the pilot light lights up somewhat dimly then slowly increases in brightness.

There is zero sound out of the radio.

I would like to restore this for our son.

I am a ham radio operator, and worked for over 30 years as the Electronic Instrument Specialist for the University of Idaho and enjoy restoring old radio. I am retired now and will be 80 years old on the 23rd of this month.

Is there any help out there for this project?

Cute little set, I have one, not a bad player. This is the place for advice.

Any photos?

Hello, Paul. Thank you for the quick replay.

I have no photos at the moment, as I have the radio dismantled so I could begin "operations"on it before I discovered the difficulty with the schematic.

I'll put it back together so I can take some photos of it, and will post them here as soon as I can.

Hi, Terry! We sure frequent many of the same forums!

Thanks,

Well, so far, so good.

With the information that Terry provided, I have determined that our son's Philco 46-200 is an early model, not a later model as I had first suspected.

It has had the PM speaker modification done. There is no "code" number visible anywhere. This would seem to indicate that this is a "first model".

With what appears to be the correct schematic I can now proceed to test components and trouble-shoot the radio.

I will post photos of the radio tomorrow.

And again, thanks for the help, folks.
