Cary,
Congrads on the successful power up. There is one paper cap i'd heartily recommend replacing as the first order of business. That's the coupling cap going to the control grid (G1) of the HO tube. The slightest leakage in this cap will cause the tube to overconduct, shortening its longevity.
If the tube is 6BG6, G1 is pin 5.
OOPs! Senior moment.
Looks like you've already done a recapping. Presumably you got that one already.
