Just wondering if anyone knows of a good bass tube amp head thats under $350. What would be my best choice in this price range. Right now I just want to push a 15 inch avatar cabinet. So I would think at least 100 watts of tube should do it. I've looked on ebay and there isnt much unless i want to shell out $900 for an ampeg or mesa boogie. I don't mind if its older like an acoustic 370 but those are hard to come by.
