I had one for about a year and loved it before selling it to another member on here. I don't remember which tubes I had, but they were an upgrade that were sold with the amp. Wonderful tone. Build quality was so much better than I expected for the price, and the sound was just wonderful. Mine blew a couple fuses before I purchased some that were a bit stronger.
I sold it because my listening area is shared as a kids play area, and the exposed hot tubes seemed like a bad idea. I've been looking at his middle amp now since it is enclosed, the MP401.
