In Reply to: Allen - would your cascode work with DHTs? posted by andy evans on September 15, 2009 at 04:58:46:
Andy,
A tube for good cascode usage needs HIGH(!!!) transconductance, which eliminates ALL DHT tubes. The perfect tube would be the Russki 6S45, second the 6H30, 3rd the ECC88.
Nothing else needs to be bothered with if you want cascode. IMO and IME.
If you want to play with 60 year old DHTs, no problem, but don't force them to work in a circuit topolgy they are not intended for - horses for courses!
