Kit 6550 resistor failures and voltage irregularities

[Richard]

Hi, yes could be, I don't know your earthing arrangement but follow it from the earth end of the cathode resistors to signal earth and check/remake any joints which look suspect.


The voltages look good now, similar across the channels and just a bit low consistent with low mains, I'd be happy with those, let us know how it sounds

Sounds great;-)

Many many thanks to all

Difficult to express just how these acts of kindness and generosity of your time makes a difference.

Now I should do same on my phono amp and a valve driven DAC I have. Both long in the tooth......
