Studiomaster EP3-24

[Brian Swatton]

I may need to try and repair one of these desks in a studio rather than at my workshop, so hoping to get info on best access and circuit diagrams if at all possible. Studiomaster can't help as archives have been lost in management changes.

Thanks for reading.

I think I misnamed the equipment, EP3 refers to the PSU I believe, the desk itself is a Series II. The beast is in the workshop now at least.

Seems to be a service manual on this page, you will have to register and join, look down under "product manuals or files":
Studiomaster Series II - 16-16-2 - manual - Another classic old studiomaster from the late 80's. This one had MIDI mute automation added.

Ah nice one, thanks. I've managed to find the fault today fortunately. Short circuit tantalum on a channel board.
