I've had better luck & reliability using solid-state rectification. Bypassing for hash and using slow-warmup devices, like Timbo posted. Not that there aren't tube rectifiers in the voltage range you are using. But, kinda getting a bit hard to find. And $$$. And still maintain long-term reliability.
You can always put a socket onto the chassis and bypass the tube rectifier (adding one later, if you find a good NOS---removing the SS portion--- or add SS inline to help alleviate some transient issues.
I know, I know--- sacrilegious, for a tube board. Just my current (sorry for the pun) experience with guitar amps.
