Howdy all. I have aquired a Philco 48-1270, which is in pretty We have figured out most of the wiring due to the minute pieces left sticking out of the plugs and such. Where we are running in to problems is hooking up the phono. We have a cloth covered coaxil cable coming off the phono and one also coming off the chassis, but the two of them don't match in color or size. Not finding any other wires of this type coming out of the chassis, this has us stumped. I did get a copy of the scimattics off the internet but the wiring diagram might as well be greek...lol. Thanks, Jim.

Hi Jim,

The phono uses an impedance matching transformer that was likely mounted inside cabinet near the speaker. The phono cables plug into to this. Hope you still have the cabinet. The phono pickup is a magnetic type with low impedance but tubes typically have a high input impedance. Impedance matching give maximum power transfer and improves fidelity.

You are taking on a tough project and wish you well.
