I cannot get a bias reading at all  for the driver but there is 13 volts at the test point. Final is ok with bias.  How can I have voltage but no current at that test point?  That indicate Tr41 is toast? Voltage on front leg of tr41 is 13 volts which I know is not right.    Rear leg varies based on Vr 10 adjustment. 


I replaced L42.  Took it out of an old cobra 140 at the driver.
