Hello again. Following on from previous posts about tape transport problems, which are now fixed, I now have a more major problem. The unit switches on , all scenes are usable, all transport functions work.
i have no audio or signals , either from tape or inputs. All I can hear on monitoring, is a low level 50Hz hum.
I think, due to a bit of carelessness, I had somehow wired up outputs to inputs when trying to use it in parallel with a computer's audio output. ( I can't remember what happened exactly). All the meters went into full RED, and there was a nasty smell. Is this likely to be an audio amp issue or a power supply issue? Everything else , tape transport, scenes, selector buttons etc etc are all working as they should. No funny smells when switched on. Something must have fried, I think, but don't know what. I would love ANY input to this problem. I have a service manual getting delivered from USA, which might help me diagnose the issue. Parts may be a problem to source ?
