Not overbearing at my seat and I don't hear it while I am playing music. I just wanted to know what part of the receiver was causing the problem? I was going to buy this off ebay.

Recapping audio equipment from the 1970s has become a big business model and it's not usually needed. Yes, the capacitance drift, but unless someone has a pristine version to compare with, It's not necessary. If it sounds
different from a newer piece, chalk it up to the fact that a lot of receivers weren't what we now call 'HiFi', but they may have fit that name at the time when they were new. This receiver is from the 1970s- don't expect miracles and don't believe people when they say/write that it was 'The Golden Age of Audio'. That's a lie and it's done to sell old equipment for more than it's worth. I have an old Fischer receiver- by comparison to newer models, it's nosiy and the sound is what could be called 'dark' (the opposite of 'bright') because the high frequencies are definitely attenuated.
The Phono section provides a lot more gain that any other section in a receiver, integrated amp or preamp, so it will generally be noisier. This can come from transistors, resistors or op-amps (operational amplifiers) and if you want, you could look into the parts used and their specs- that's about the only way you'll be able to find their noise specs IF you want to make it more quiet but the fact is, you should never need to crank the volume to max for ANY source input. This has carbon composition resistors and they tend to be noisier than metal film or other newer types.
Here's the Signal to Noise spec from HiFi Engine and by comparison with new equipment, it's not very good-
"Signal to noise ratio: 55dB (mic), 65dB (MM), 75dB (line)"
