Hi all
I have a retro Amstrad studio 100 Hifi in my mancave vintage computer room which I love but its not working as it should the record deck is playing slightly slow and if I click the Hifi onto tape there is a loud feedback noise which does die down after a couple of mins anyone have any ideas where to start to try and sort these issues please.
many thanks

Your unit is 35 years old now and the Drive belt for TT may by now need replacing. This unit is crammed full of controls, meters, lamps and whizzos - it might be the "reverb" feature that is causing what you call "feedback".

I have had one of these from new back in '89. Common problems were the relays on the 4 track deck causing oscillation, and the rec-pb slider from the upper deck might also need a clean. Ditto the main mode switch (DJ-HIFI-STUDIO).

The Tanashin cassette mechs really were not man enough for the job, especially in the 4 track unit. New belt and pinch roller will cure erratic speed - for a while!

Likewise the sliders were fairly cheap and nasty, and tended to go crackly very early, so some servisol on these and the relays mentioned earlier would be a good idea.

Where would I find the belts and Piinch rollers for it As there is a guy on eBay selling them but he is quite expensive.

Just order a mixed lot of square section belts, it would probably be cheaper. Will try and find the reference to that Tanashin pinch roller too.
