Therein lies the most likely problem. Do you have a scope capable of probing the B+ to the output transformer? If not, post the schematic of the power supply and let someone here run a SPICE analysis. We'll need the value and DCR of all chokes, the approximate current drawn by the output stage and (if possible) the ESR of the filter caps.
