So I saw a post about DIY amps on another forum, and checked out some of the links that got posted and now my curiosity is getting the better of me. So I checked out something like Pass Labs Son of Zen project, the parts list is pretty small and it looks to be fairly simple to build/test. I'm just wondering what kind of results one could expect out of something like this? It looks to be an interesting design, scalable from 5-50 watts (by just pumping up the power supply), Class A operation, zero feedback, etc. My biggest worry would be how to dissipate the heat (build it to 50Watts and the power supply needs to be able to give 1200Watts all the time), look like it could heat a small room...or setup a home theater (5 channels) and heat the house while you watch a movie. Maybe yank the compressor and cooling stuff off an old fridge...hmmm
Also, LCAudio has an amp kit out, but it's a digital amp, 90% effecient, big power (200+watts), small power supplies, low heat, etc. This one looks interesting, and is fairly cheap for what you could potentially get.
I'm not so much looking for money savings, just something to do that's less messy then making sawdust. So how hard is it to construct some of these things? I have a bit of experience building kit based electronics (remember Heathkit?), but nothing to this magnitude, although I helped assemble the infamous DIY TV from I think Heathkit or was it Zenith, many years ago.
Any comments?
