TINY amplifiers?

[Bake 10+ year member]

I have a tiny little Blaupunkt amp that claims 20 watts per channel rms.

the 386 is decent if you build it right.

I'm sure you already look at this site which will give you better answers on what you're looking.

Thread revival, woo!

Actually, this project was abandoned in favor of a tube amp. Which every time I replace a faulty part, it makes it obvious something else is wrong with it. =\ Either way, I don't really need another one, but I might try building a CMOY for fun, as long as I can build one that will handle 16 volts.

What's up with the amp?

I recently bought and am restoring almost the identical project you have - dual pentode-connected 6BQ5's with a 6CA4 rectifier. Let me know if you've got any questions on it...although I'm mostly doing cosmetic work for now, haven't really torn into the guts of it yet.

Well, I removed the pots and replaced them, that helped A LOT. An incredible amount. Then I replaced the caps, and something odd happened. The music cleared up a hell of a good amount, but the buzz that I thought was bad caps got worse! I'm currently not using it, the buzz got so incredibly bad. I'm accusing the power supply, a huge transformer, for the problem as of right now, but I plan on working on it's ground connections first.

I need to get a new soldering Iron. The Radio Shack ones are complete junk. *grr*
