Funjindemon,
That's what Tennessee Williams made the bad $150 for...
I have halo's on my amps on the small tubes only. It had a remarkable effect. It so tidied up the sonics that it sounds much more like ss in the clarity of tone rather than the highlights and harmonices that were present before, which I believed was "tube like". It's nearly amazing the effect on the Tenor 75's. I haven't a clue what they'll do for your preamp, but it had a greater effect on the system than any other single item that I've been able to think of.
