I am working on a Philco 41-616 Remote Controlled radio console.  The chassis has been "butchered" somewhat.  Knowing nothing about the specific details of the mode switching relays, I need some information.

Foe example:  When switching from Radio to Phono mode,  what functions are switched, such as oscillator screen, audio,  detector output, etc.  Does anyone have any data such as:  When the remote control switches to Volume Control, relay Kxxx is energized, connecting grid of Vxxx to terminal xxx of TB xx.

I have a pretty good grasp of the theory behind all of the circuits, but am completely lost in the physical details.  I have an excellent set of schematics.

 

Any guidance would be much appreciated.

Hello,

I see Your problem, but I fear there will be nothing around to satisfy Your demand. It is certainly one of the most complicated sets in its time.

There is of course the schematic (You have the papers), but the circuit analysis and derivation of a table for the switching logic is quite a job. That is not done in one hour. I guess two full days might be more realistic, if done with the necessary care inclusive full verification afterwards.

I fear there will be no reply. I can only hope for You that I am wrong...

Nevertheless: Good luck!
