I had one of these years ago and traded it on the 5153 mini head. Wished I would have kept it, gets nice floor chunk at lower levels. Given the size of venues we usually play, I kinda missed it. Found a good used one today! Only issue is static for the first 20 secs after releasing standby. Once it warms up it's fine. Changed some pre tubes. Haven't tried power tubes yet. As long as it sounds good and works fine I don't really care. Killer gain.
