I have owned 3 of these. Every time I sold it, I would miss it and buy another. I have currently owned my last one for approx. 6 years with not an ounce of trouble. These amps are built to last and do run hot as they are biased heavily into class A up to about 20 watts. If you can afford it , go for the mk2. better midrange and fuses for each output tube. Otherwise, get your feet wet and go for the mk1. Best tube is the EL-34, which is the tube Modjestky designed around. Will drive TSM's without even breathing hard. I would contact Bobby first though. He might reccomend something different and less powerful.
