SAC-Thailand: 6SL7 + 2A3 _ GM70 SET from a custom order
SAC-Thailand: 6N1P + 6BL7 + interstage to two GM70 PP=70W


This does not play, I do not recommend heard these amplifiers
OK, I think I understand what you mean, as 2A3 is much hot and sirupy, etc, 6BL7 could be the same character too.

it just does not play:)

Look this SAC 2A3+GM70 amp at underside, I see it use a interstage trafo, to up the signal.
