RE: what driver tube to use when running PP Triode 6AQ5s?

Posted by sony6060 on January 11, 2017 at 13:34:38:

You cannot beat USA manufactured Raytheon 6CG7 black plate, but are rare & almost all used are unbalanced due to hard use in TV sets. An alternate are Sylvania 6SN7GTA. The Sylvania have a hotter high frequency response, but extremely clear sounding vs other 6SN7s.

Only 12AT7s I recommend are Sylvania 12AT7 triple mica grey plate or for a more neutral sound are Tung Sol 12AT7 black plate. Some are noisy, but quiet Tung Sol stay quiet.
