Sony PS 4300 turning too slow

Post by Kimbo2 » 15 Jan 2020 18:18

Last year I re-acquired my PS 4300 after it had been in storage for 30 Yrs. Bought in 77 & last played in 89. It had played perfectly for the last 6 months then abruptly started spinning slow after I noticed I forgot to turn off the power switch after prior use. It had been on for about 3 days. I read and old post about another PS 4300 that did the same thing after being left powered on and the recommendation was to use Deoxit on all of the speed pots and switches, which I'll try tonight. I also heard others say a cap could have blown. If the Deoxit doesn't work how hard is it to diagnose a cap or transistor problem on the boards? or change one if found? Thank you in advance for any help here....
