1950s Magnificent Magnavox HI-FI Console issues

[Captainclock]

Hello everyone, today a buddy of mine who has been a regular customer of mine as far as bringing me stuff to repair for him for his booth in a local antique mall has brought for me to work on a 1950s Magnavox Console that has a seized up record player (the power switch/reject switch doesn't work and neither does the speed control switch) and it also had a partially seized up function switch and a fully seized up bass control switch as well.

Anyways Part of the record player is attached to a switch that's mounted to the cabinet on the inside of the record player housing area and I can't figure out how to get that switch unmounted from the cabinet so I can take the record player out of the cabinet so I can tear it down and relube it, any ideas as to how I could get the switch out of the cabinet?

Also when I was trying to free up the bass control switch I ended up accidentally busting it (the wafer which the switch would ride on to make the different bass setting connections broke in half and it seems to be made of a thin wafer of plywood) and I'm not sure how to go about fixing the switch, should I just try and find a replacement switch for it on ebay from a similar Magnavox chassis that's being parted out or is there a way to repair the broken contact wafer and have the switch still work? Also what amplifier does this thing use? Is it one of the more well known and famous Magnavox amplifiers or is it another one that they used that wasn't so well known? The tube compliment on it if it helps is 4 6V6GTs with a 12AT7 tube and a 6V6GT with a 6AT6 and 2 5U4GA Rectifier tubes.

Any assistance would be helpful.

Thanks,

Levi
