Hi,can anyone help with problems I have with a first version of the srm1 mk2 amp.The offset stays around -120v and adjusters have virtually no effect and the balance of the right channel stays around -30v with adjuster having hardly any affect.I have changed all the electrolytic caps but not the blue and brown film caps.All the resistors seem to have the correct values.The bias voltage is 175v,is this ok but the bias resistor is 3.3M which I think is wrong.Thanks in advance for any help that you can give.
