"Bring Out Your Dead"
I have possibly found a solution to the dead MB8841's. On the theory that the Mb8841'a reset switch was not getting enough juice(voltage or current) to reset,.... AFTER RECAPING WITH HIGHER VOLTAGE CAPS..... I was able to get two dead PS-X'S a 65 and a 75, with dead, ie no lock, spins backward, to reset and function! My solution was to raise the voltage with a "variac" to around 130vac. This for my turntable raised the voltage at the reset pin(2 or 3 I cant remember) to just around 5vdc(4.98vdc,4.92vdc). On the PS-X65, I had not recapped and started to smoke various of the 16vac cap's.
Both turntables have been recapped now and are working mostly well(speed locked and keys functioning), and long process of fixing the tone arm grease and adjusting has begun.
It may be possible to directly increase this pin's voltage, I will leave that for smarter people.
