I did replace the dual 50uF cap with a brand new JJ dual 50uF 500v- the hum is even louder!!! I have used JJ caps before and I have to say they are excellent.
I did replace V3 with a Mazda ECC83 which made no difference.
Which heater tap shall I disconnect?
The only thing I can think of now is that there is something seriously wrong with the power transformer OR that the new replacement transformer is showing up an issue that may have existed in the original amp design?????
