MU524 Vari-Mu Tube Compressor / Re: Different output levels
« Last post by Elektrovolt on August 20, 2024, 02:28:42 PM »Thanks JP,
I was already suspecting the input potentiometer tolerance, they measure a bit different from each other. The transformers are mounted correctly and all audio path resistors are correct also.
The pots measure:
Full values are 9,7 kohms and 10,8kohms
Wiper set exactly in the middle: 0,95 kohms and 1,08kohms.
So there is a difference between both.
I do have some good quality log pots 25k from a Sound Devices mixer. Would that work too, (with an 18k resistor between pins 1 and 3) or should they really be 10k?
