back to the Tenor OTL’s; eventually Tenor went bankrupt; but the good news is that another group bought the assets and raised it from the dead, and the 75 watt Tenor OTL’s got their design cleaned up and did become reliable......and i would strongly recommend a set if you can find one (and make sure it was built after 2005 or upgraded.This statement seems to be incorrect. To the best of my knowledge they only make solid state amps; I'm sure we would have heard about it if they still made OTLs.
FWIW the MA-2 Mk2.2 dates from about 17 years ago... and in the intervening time we have managed to make some progress :) The current incarnation of the MA-2 is Mk3.3. People have described the improvement as a 'transformation'.
