When the filter capacitors don't filter any more, then B+ can reach 400+ volts. The increase in plate voltage causes higher than normal plate current which also flows through the transformer primary, poof!
The Hammond 125D was my target. It's a universal 10 watt and accommodates the low H13 speaker impedance. I ended up getting an OPT from a Philco speaker at a garage sale. BTW don't get the one on ePay for $40. The seller is foreign and has no control over his US inventory. Read his feedback.
