Well, that is very weird, and hints at still unresolved problems.
Transformer tap voltages do not change on their own, and with 4V on filaments that amp would never have worked ... or worked so poorly that nobody would buy it.
That amp has all voltages regulated (even +V) , very unusual, and that may be hiding a very wrong transformer connection.
Only unregulated voltage there is power amp filaments.
I wouldn't worry much if I found, say, 5.9VAC or 6.9 , but 4V is gross.
I'd love to know DC voltages at:
C38 and C5
C55 , C19 , C41
And please reread filament voltages, straight from pin2 to pin 7 on power tubes and across (tabs?) WC5 , WC6 .
Something does not add up here.
