Hey all
I have a Technics SP10 Mk2 which is giving me some speed problems, it would lock onto 78rpm but not 33 and 45rpm. I have checked voltages on the power supply and they are all correct, I have also swapped all the boards inside the turntable with spare ones I have except for the logic board which I don't have a spare of. I also replaced all the electrolytic capacitors on the logic board but the problem still persists. What else could be causing this?
A little history about this particular SP10: I bought it as "non working", the logic board was damaged. After some months I managed to find replacement boards, I swapped the faulty logic board with the new old one and the table was running fine. 33rpm and 45rpm locked on to speed and ran fine, 78rpm was not getting up to speed but I thought nothing of it as I do not listen to anything at this speed. So I started building a plinth, mounted the table and tonearm and switched it on. Now 33 and 45rpm wouldn't get up to speed but 78rpm was fine..
