First Amp Build

russellw70 · 7th March 2010, 08:19 PM

Hi All,
I've been lurking for a while and now have the desire to try and build something.
After a bit of looking I have found a simple 3W amp design, http://i263.photobucket.com/albums/i...link/3WAmp.gif. This appears fairly easy and would fit my needs. Is anyone familiar with this design, any comments or any recommendations? I will be doing a turret board layout for the amp and would like some input when it is complete, any takers?

The PSU looks fairly rough to me, the rest seems... the coupled input, the small coupling cap, no gridstoppers... a little odd, I'd say.
If I were you, I'd look into
stereo SE kt88 build ... abdellah diyaudioprojects design
It's a project with a quite similar part count, but tested and most likely better.

Thank you for the advice, I'll read through the thread.

well okay i see from the other thread that you've gone the other direction so really only wish of good luck from me for now.

what i did want to add for anyone else is that those 6bm8 things should be all over the place and there ought to be plenty of "proven" designs out there for anyone seeking them. in particular, i remembered something from the old svet page that seems to be reposted here under figure 2:
