Welcome to the Phono forum Kati !
1. Please also post the model number of the Philco, and we
can supply you with the circuit and V-M made record changer
manuals for service use.
As others said, it must have basic electronics serviced.
2. The Philco has a combination needle/cartridge which
plugs in to a mount in the tonearm.
The part is a stereo Astatic 13-T type.
These cartridges are now expensive, scarce, and they
actually do not play that well, in my experience.
3. What we recommend is to replace that cartridge with
a modern Pfanstiehl P-226 stereo cartridge.
https://thevoiceofmusic.com/catalog/par ... ategories=That will take a person to have some knowledge of
how to wire up the new cartridge.
I recommend you find a local vintage radio club in
your area, as there will probably be a member who
can install the new cartridge.
They could also do the electronics service.
The new Pfanstiehl will play very well in the Philco,
and is not expensive.
Once the servicing is done, your family's Philco will
sing again for many years.
Ask more questions, we are glad to assist you !
