Jap, The 1 ohm idea is fine in theory.....

If I measure from one of the testpoints (the tipjacks) to to the center testpoint between the output tubes, I get 1,2 ohms, which means I have to deduct 20% from my mV readings.

Hereof, a measurement om 25mA (mV) actually means 21 mA - a pretty severe error margin don't ya think??

Whats the moral?? use your freaakin' ears to bias an amp

Great, that your amp i working. I have just put my amp together, but is waiting for the choke and pt from hammond mfg. Which wires did you forget??
