Hello. I had good luck with a guy named Randy Bemis, who contracts out of El Rayo Guitars on Adams Avenue. Randy's direct e-mail address is:
randy@bemisamps.com
Randy addressed my Mesa/Boogie Buster Bass 200 head's tube issues. I don't know if your cabinet problem is the kind of thing he'd take on.
If you contact Randy, go ahead and let him know Joe Gillis sent you. He'll probably remember my amp. I think he even went to one of my band's shows at Humphrey's!
Cheers,
--Joe in San Diego
