Vintage tube audio doesn't need to get involved, except for 
the old-style twist-lock Mallory cap design.
All the off-line switching supplies use either 250 V (120 
supply only) or 400+ (120/240 supply) capacitors as the main 
input filter. So, at least, capacitors in that voltage range 
are STILL being made, and are in all computers, TVs and 
other home appliances.  (Yes, I know the OP needed a 30 V cap.)

So, some other tube gear replacement parts may be scarcer 
than hen's teeth, but the HV caps are easily available.
