Yes and it passes.
Sams Says 550 v on the cathode of the 6W4 & 280 v on the plate of the 6W4. When measuring the cathode, is that where you got the 355 volt reading? the voltage on the plate of the 6W4 is supposed to be 280 v & is 20 volts low.
if the cathode of the 6W4 is reading 355, it is too low & is a possible indication that something in that immediate circuit is drawing too much current. after all, that is the B-Boost circuit. that also could be the cause of the low B+ voltage (250v)
