Two versions of the original ALPHA SEVENTY were offered. The 70V is the
vapor-cooled version which uses the 3CV1500A7 and the 70A
was the air-cooled version, using a 3CX1000A7. Both amps offer instant-on
capability with the air cooled version offering somewhat
less power and plate dissipation as it's vapor-cooled counterpart. Both amps
were built using very high quality components and
very much resemble the model 77Dx in appearance. I believe production began in
early 1970 and ended in the mid '70s. You can find
more information at the Alpha legacy amp web page:
