[TenTec] Centaur Tubes odd ones in parallel

[Katz Ajamas]

Kris-

Are these 811 or 572?  I've never owned a Centaur but have not had any
trouble with non-matched tubes in other amps, provided they were from the
same OEM.

A single used 811 or 572 should be pretty cheap, so how about hunting up
one each of the missing?
