Default Stable 10 Watt Amp

Here's that 10 Watt 2 X TDA2003 Amp I built for my record player project. Proper ground wiring resulted in an amp that was completely stable under all conditions of my usage!

"shorted turn" alert!

google that concept and remove that yellow wire. that's not a place to tap into chassis!

No need for Google. There's no complete circuit around the core of the transformer and hence no shorted turn.

I do take the point that there's no need to earth at that point though.
It was just a handy spot to use during the build and testing when parts were being moved around. I have a much more appropriate and neater location for that chassis connection in mind.

if you are deriving ground from the mounting bolt on top, it is a shorted turn.

it may not be as very bad one but it still meets the def, I think.

just wanted to point it out. other than that, I like the layout a lot.

I'd also remove them, or if you insist, run them from undeneath the tranny, so it doesn't make a loop around the core.

Beautifull work b.t.w.

Hi Howlindawg,

I like your AC in cable. What is it and who is the source?

Hi Bob,
