Hi,
Can anyone help me with this amp model GK400b.
Has been worked on before.

I need to find the values of 3 resistors burnt beyond indentification.

1. R3
2. resistor to junction off R21 and anode of D2
3. resistor to collector of Q6

also the output and driver transistors.

Any help is greatly appreciated.
Thanks
MP

Try this one on alt.guitar.bass. There are several GK RBx00 owners there.
