The PHILCO Phorum

Dear Friends
I have had this radio for around 5 years and have not hear it yet working. Five people have worked on it with no success. The last one was closed to get it working but, he got sick and was not able to continue working with electronic apparatuses for safety reasons
The last status he gave me was:
"The last known condition I witnessed on the bench, I could inject an audio signal at the volume control and had great audio through the last pre-amp and push pull amplifier circuit.
The original speaker sounded very good. I was able to inject RF signals at the front end(antenna connection) as could trace it up to and basically through the the oscillator circuit but the signal was not being coupled to the audio circuit
I suspect that the oscillator tube or something else in the oscillator circuit has now failed and will not allow proper signal get through"
This guy worked with
The caps
The bad resistors
Potted Bakelite components that house capacitors
A bad tube socket
Bad wiring
And replace all of the tubes

Now my radio is in the hands of another technician.

Question

What should I ask this Guy to check on? Which is the oscillator tube?

Do you think as I do that it should be very close to have this radio working?

Im attaching a pic of the cabinnet

Thanks for all your help

<What should I ask this Guy to check on?
If he's worth his weight in salt he should be able to troubleshoot it without any advise on what someone else thinks may or may not be the issues.

<Which is the oscillator tube?
The 6A8G. There is a 6N7 that influences the oscillator via the afc circuit.

<Do you think as I do that it should be very close to have this radio working?
Lots of variables involved. Might be proprietary parts that aren't commonly available. Depends on how sharp and motivated your tech is. Could have an open coil or two in the rf deck (not all that common on the post '35 set).

Thanks a lot
