Interesting! That's a little bit "low tech" compared to this: http://www.letstalkguild.com/ltg/sh...Your-Own-Amp-You-know-you-ve-always-wanted-to-!

I have been wanting to build a champ forever! I'm scared off by the high voltage, but the circuit really isn't that complex. I'm planning to add a tube preamp eventually to the amp I am building and using the same LM386 chip as the power amp. If anyone is interested the circuit is available at www.beavisaudio.com.
