Hello Igor,
?
some of your screens show input voltage of 12.8v. ?Others show 11.8. ?Is that what you see there? ?Is the supply voltage being reported inconsistently or are you varying it?
?
also the bias should always be steady at 30ma. ?The QMX is actually reading a voltage which (if everything else is right) should correspond to bias current. ?So this is an indication that something downstream of the bias circuit is not right.
?
whenever I have a repair where the output is consistently too low, I get suspicious of T501 - the output transformer. ?
I think I would track down each of these anomalies thoroughly and separately.
?
let us know
