I have a Great American Sound Thoebe preamp. The unit works and sounds very good, but however: it runs extremely hot. Unless I have the cover off, it will cut out after a period of use.
It seems that the power supply regulators are the prime cause of the heat. I suspect that the transformer is not original (there seems to have been done a rather clumsily conversion from 110 to 240V somewhere along the line).
Do anyone know the transformer rating (output voltage) for the original Thoebe? And the correct regulated supply voltages?
Thanks to anyone that can help.
Regards, Espen
