Yep it's definitely gone for 95%. The "rest" is hum from the speakers but it's WAAAAAYYY silent compared to the transformer(s).
Anyway, still opened the amp and controller units to have a look today.....because I felt a 40 year old machine might need some new caps.....
Going to be an expensive cap-kit !!! Of course they are all axial. They actually look amazingly good for their age, no leaks....
I think those big one's might be paper caps.... look at the date-code on the biggest one, 7026 (1970, week 26)....almost as old as I am
Gonna be fun to measure them tomorrow, I'm _really_ interested in what they will show
Replacing is going to cost......axial is already much more expensive and I guess I'm going to want some audio-quality one's for this baby....
Just another picture:
The bottom (or top ?) side of the amp.
The switches from top to bottom:
-scratch compensation (of course turned on minimum)
-treble (three positions)
-bass
-record equalization, not sure what this exactly does...
All of them will need some good cleaning, maybe replacing. They sound scratchy when moved. In wrong position (half-way between two "selections" f.i.) it definitely influences the sound quality....
THe terminals are for the speakers. Need to find out why the right bass speakers isn't working....
Planning on replacing the speakers (in due time). I think it can sound a _LOT_ better with some better quality speakers....
