yeah; there is tons of info on that amp and most of us own them. For 25$ we can afford them. They sound good; just don't push them, they have a threshold; exceed that and they get shrill and harsh and nasty. If you use them with a good efficient speaker and listen at reasonable volume they sound pretty good. The best use for them is for bi and Tri amping speakers. Use the T-Amp for the tweeters and then buy or build a Gain-Clone 30 watt job for the woofers. Total about 120$ and you have a real good set-up. Hope I didn't stray too far from your original question. If you search on the site there are lots of messages regarding those amps.
