Hi,

I have recently acquired a Technics SP10 Mk2 direct drive turntable from 1981.

It came from a radio station so I presume it has spent most of it's life in an air-conditioned studio.

It has a quartz lock system with a number of circuits including a quartz oscillator, frequency generator and phase control ciruits.These are based on (74xx) ICs and it has (x16) (74xx) IC's and (x95) transistors on 3 boards.

Recently I was attempting to connect some oscilloscope probes to check the control circuit as per the manual and slipped and shorted...

Hi,
I found this site when looking for capacitor information.
I'm mainly interested in audio and diy audio including turntables, DACs, preamps, power amps and speakers.
I appreciate the opportunity to join this forum and though I came here to seek information and advice on a specific topic I also hope that I may be able to contribute something meaningful for the benefit of others one day.
