Rotary wafer switches are one of those things you don't want to ever break as repair/replacement is rarely easy/simple.
As for the knob: have you considered stealing the spring clip/retainer/shaft grabber off a random junk knod meant for the same type shaft and gluing it into the old knob.....Hell if the plastic shaft of the damaged knob is thich enough you might be able to make it into a set screw.
This should teach you a lesson NOT to force knobs. I destroyed a wafer switch once by forcing a knob....The lesson I learned from that I will never forget.

well first of all I didn't know it had that kind of control in there I just assumed it was a regular pot that had a bearing in it that allowed it to "click" into the different positions that it needed, can I even find a new switch like that anywhere?
Secondly as for the turntable speed knob I didn't realize it was that badly stuck to the point that it would end up stripping out the knob (its rounded out right where its supposed to be flat) and that the retention spring would break because of that.
Also, no I cannot use parts to make the existing knob work because I don't have any old turntable knobs that are of the right style, I have some knobs from an old Voice of Music made Zenith record player but the hole for the control isn't the right size and the retention spring isn't the right type, its the kind that fits into the hole and not around the hole like the knob that originally went with this record player needs.
UPDATE: I looked over at Mouser and Digikey and it appears that they do have some switches like what I need for the tone control on this Magnavox, the only problem is that they don't have the right kind of shaft shape or length. the kind of switch I need is an adjustable 12 contact, 4 position switch that has a shaft length of of about 1/4" or a little longer and has the half moon shaped end so that the original knob can fit it on it.
