Alpha 274

This amplifier is one of the original 274s with two 8874 output tubes.  There were a very limited
number of these amps produced.  I have been told the number was 18.
It was later modified to use three tubes.  The modification was done with factory supplied parts
and the exhaust plenum was modified with a nicely made extension. 
Being a purest, I talked to the factory about restoring this amp to two tubes. 
They suggested I leave it as is.  It would probably do more harm than good messing around with it.
