Hi, I'm new to this board and did a search on the SS amp. I can see alot of you guys love them. I picked mine up brand new from GC last weekend and love it with the exception of the Vibrolux channel. I play alot of Skynyrd type stuff and it is great. I noticed some people saying the amp came with cheap tubes, not biased correct etc. My amp was loaded with Groove Tubes and the bias was a little cold at 27 and 29 respectively; I adjusted it to 32-34 ma. What tubes did all of yours come with? Just curious.
