While I respect Hiend2 and Eldarado on most AGon forum references, I have to disagree with them this time around.
I have the large stepped attenuators which are easily dealt with AND I had to contact AI service for brass screws which I had misplaced from tube rolling. The AI service assistant mailed them for free within days.
IMPORTANT: Do not use this pre-amp with the supplied Sovtek tubes. Anything you replace them with will sound thousands of times better. Even a donkey. (Perhaps this was Eldorado's "sound was ok" problem).
Also, do NOT ever turn this pre-amp off. The tubes definitely last forever by having them constatly warm. I'm talking 4 yrs my Cca's have been running like new. I can't explain it.
