Gavin:
For your first question, isolation seems to be the key - I've heard stories
of people like Pete Curry using bungee cords to isolate the tank in a
frame-like structure . . . I'm sure others on the list will have some actual
field-tested solutions.
I'm assuming that you have a RI tank (I forget, I'm sure you've mentioned it
before . . . ) One non-invasive technique to take the edge off of the
treble is to replace the 12AX7/7025 tube with another 12AT7 (NOS, of
course). The 12AT7 has about 70% of the gain of a 12AX7, so it really tames
the screech, but still allows the tank to sound great. That's a quick,
easy, and reversable cure, IMO. Also, I think if you back off the dwell and
mix controls to below "7", you should be able to turn the tone pot up
without having your ears bleed. However, that may sacrifice some of the
sproing you're looking for - try using the 12AT7 instead of the 12AX7 - I
think you will be pleased with the results.
Good luck!
-Dick
