Dear,
I have a hiwatt Custom 100W DR103 ´70 .
I add a new power tubes and the bias current is 50mA. I change the bias resistor 47K (-36Vdc) to 220k (-44Vdc). But the bias current
it is still elevated. I tried to put 330K bias resistor bit the voltage no changed.
How can I down the current of polarization?
I am doing something wrong?
thanks, regards
