Hello, I picked up a Beocord 2000 that had melted belts. I ordered those plus the idler pulley rubber and the R8 resistors from Danish sound parts. I got all that mechanical work down and now I am experiencing intermittent slow downs in play speed. When I read the voltage at the motor, normal speed will be 14.77v for example, then I’ll hear the music slow and watch the voltage on my MM drop .2-.8 V’s. I’ve essentially swapped every capacitor that is relevant, and put in a new regulator nearest to where R8 is because I used a thermal imager and the regulator plus caps C4 + C5 were showing hot. In addition TR19 and IC9 were also hot and warm on my imager respectively. is there a known issue that would cause this that I have over looked?
