Saw it while driving by. I stopped and looked into it. Blue label SVTCL. The lady of the house said it's broken. I ran home for a cab and a bass and went back. I warmed it up and spied on the bias lights. They were all green. I plugged in and slowly turned the gain and master. It makes this squealing sound. I figured, heck it's probably the preamp tube. Worst case scenario I have to use an outboard pre. WTH, I have a Sansamp anyway. I forked the $$$ over. Drove to the local music store, bought three 12AX7s just in case. Three new pre tubes later. She works! I couldn't believe how noisy the fan on this thing is but it works and it's loud! I'm thinking about selling it so I can get the tube amp I really want. I figure this will go quick for $600 to $700. But part of me wants to hold onto it because, hey, I put some time into it and that makes it somewhat special. The Aggie's liveliness balances the Ampeg's tone well.
