I was looking at the service manual for my vintage (OK, old!) Denon turntable, and I was surprised by the amount of capacitors, resistors and other electronic stuff that's in a turntable. (I guess I never gave it any thought.)
Is that stuff just related to speed control and other turntable operations, or does it have something to do with the signal?
Again, I hadn't given it much thought, but I always just imagined that the signal pretty much went straight from the cartridge to the turntable output, and didn't go through much in the table.
And, if the electronics in the turntable are signal-related, can/should they be upgraded?
