An update. Dave Vidal doesn't really do ampeg amps anymore, at least not svt's, he's just been too burnt out the last time I talked to him. He enjoys working on Fenders more and did a great job with my YBA-3 and I will probably ask Dave to help recap my B15N. He also recommended Minsoo for servicing my SVT. Ho's good too.
Folks at VASC are really nice, but Dave Lee, the owner, just passed away this past weekend, so I'd probably take speaker repairs to Kinetic Sound. Backline is very professional, but their bench rate is quite high.
