    I recently ran accross some amp kits, including inexpensive reamp "based on" time-proven, classic designs, as well as what looks like a decent 6L6 SET amp for a little over $300. I was about to post a message to see oif anyone had any experiance with them when I found the thread pointing out that these are pirated designs, and "based on" means "filched from".
    
    I guess I was thinking of the really classic ones as being beyond patent and in the public domain. But that doesn't hold water, especially given that some, for instance Transcendant Design Grounded Grid pre, are pretty new, and clearly innovative. And I cofess, I am a lawyer, and should have known better. But I only do criminal defense, and haven't looked at patent law since the bar exam 30 years ago. So there.
    
    But some of the designs., like the 6L6 SET, ape no propritary design that I know of. Now, I could easily be wrong here. I'm no engineer, and that design may well be the patented fruit of someone's labor; then again, it could be based on some 1930's design, long passed into public domain, like, say, old RCA designs. It IS a SET, afterall.
    
    I know, a strong argument can be made, and I'm sure someone here will make it, that if DIYaudio, or whatever they call themselves, pirates ANYTHING, they should get a wide birth, and not a sigle dime, from any honest person for even honestly marketed gear.
    
    But I'm on the fence about the SET kit. Can anyone tell me if that circuit, too, is stolen? If so, I can simplify the moral and proceed straight to "Eat Excrement, DIYaudio company."

      Very little chance to be so. Tube schematics are very typical, a few of good books/magazines published back in 195x/6x cover almost every schematic topology imaginable, in other words, there is nothing to patent, may be except some very exotic hybrids.

    I have heard quite a few people using these:
    http://www.transcendentsound.com/preampkit.htm
    who were quite pleased with them.
    Cost just a little more @ $499 for full kit.
