Dear friends!
My old FL2100z just does not work... I get nothing out, tubes
are OK when checked in another amp. The only thing that
happens is that I now have around 50 mA Ip even with the
switch in stand-by position. The R5, 820 ohm resistor for
bias is burned and shows 670 ohms, should be 820 ohms.
I did replace it, but no change. The input from the transformer
to the PB-1903 circuit board is correct, but only around 6 volts
bias out from that circuit board.
Any hints what to look for. Please answer direct to
sm5dqc@algonet.se
and when I cured the problem I will let you all know. Many thanks
in advance!
