I sold my 20W 6505MH and this is the practice amp I want to replace it. I actually played one long ago when Sam ash was still a store. No concerns for burning the big expensive bottles for random playing.
Not sure if you're still in the market or of the going rate or whether that cab bundled with it is of any value compared to the price (USA, Birch, and V30s or T-75s, from what I gather), but came across this after remembering your wtb ad.
If you find one let me know please - this is a dream amp of mine and they didn’t make many. I can also obviously repair a broken one if you find one for parts.
