Philco 625B Assessment (UPDATE It works!)
#39

I am working off that particular schematic Ron. Thanks for having it available!

I am facing a major decision here. This particular chassis has been pretty heavily modified in the past. Resistors are different, capacitors are different and a lot of the wiring has been modified also. This, along with the fact that a lot of the existing wiring is in really bad shape is making things exceedingly difficult for me to try and figure out what is what on the actual radio vs. what should be according to the schematic.

My gut instinct is telling me to take everything out and just rewire the radio from scratch. To my inexperienced eyes, this is a pretty complicated schematic - but it's doable. As I wire a component, I can highlight it on the schematic and move along.

What has me completely stumped is the rotary switch positions and wiring up the coils to the proper switch terminals. Lastly, on the antenna coils, I do not know which coils is AM - Police - Shortwave. The top coil is largest, so I assume that is AM? The middle coil is SW? The bottom short coil is Police? I have attached a photo.

Finally is there a standard way to identify the terminals on the bottom of the coil using an ohm meter? Is there a diagram someplace from Philco that shows this?
Any help and advice is needed and most welcome!
Thanks folks!
