you should be absolutely certain that the first stage is VERY well
filtered, even below 20Hz. Hammond makes a small 60-henry, 8mA
chome which sells for about $10 each U.S. If you feed each 1st stage
with one of these, along with a minimum of 100uf filter capacitance
(prefferably 200uf or so), then you may totally transform the sound
of your amp. Seriously --it makes a HUGE difference, and most SETs,
(even otherwise good commercially made SETs) somehow seem to
over-look LF stability/ feedback issues.Try it, and you will thank me.
Good luck!
