Hi, I am selling my SoundTrack HIFI 130 Mark II 25 watt class A stereo tube amp. I bought this amp new exactly two years ago. The amp sounds great and is in good physical condition. The only flaw I see is a small indentation on the lower left side of the front plate and a little paint damage in that spot. It can probably be re-touched with a tiny bit of black gloss paint, if you are a perfectionist. Otherwise, the amp looks really nice. This amp has a total of eight (8) tubes. There are four 6L6 output tubes made in Russia. l will include four extra 6L6 power output tubes! The front panel controls are Timbre, On/Off and Volume. The amp also comes with a black tube shield that can easily be removed. The amp is heavy for its size. It weighs approximately 15 pounds. You don't need a preamp to operate this amp, although a preamp would add more contour for treble and bass. I used this amp in my home with a Dared SL-2000A preamp, which I have already sold. I have decided to go back to solid state.
