Out of interest I removed the 50 ohm trimmers on the RGD- one reads 318 ohms, the other a whopping 694 ohms! No wonder the thing sounds sick. It looks like this may be the heart of the problem as I can't find any out of tolerance resistors or dodgy caps.

I shall source some new trimmers and go from there I think.

Thanks again to everyone for the contributions so far.
