Since when are they plentiful? Last I looked they were becoming extinct as Russian surplus ran out.

If they are in current production that would be great but converting a triode amp to tetrodes can be more trouble than its worth. The GU-74B (600W in reality) socket is huge.

The 3CX800 is becoming a premium and "hard to get" tube... have you considered modifying the Alpha to use 4CX800 (GU-74B) tubes which are plentiful and cheaper?

Hello all,

Recently picked up an older Alpha and was thinking of making the conversion to a pair of 3cx800's from the 3 x 8874's which are in the amp.

Any suggestions on a source for good 3cx800 pulls?
