Low Output Help

[coolidgeamps]

Nice! I remember I liked it, I forgot it wasn't on the casing. Very nice work (as usual). Lol, don't let Craig see you spell bus that way.

Which star ground is it connected to? I assume the preamp has it's own?

When a ground bus looks that good its called a buss. The ground schemes for this ODS amp vary from schematic to schematic but most have a star ground for the preamp at the preamp end of the chassis.

Side note: I never lose a lead. I clip with one hand, and I hold the piece I'm cutting off with the angled pliers.

You SO just jinxed yourself, report back after.

lol, probably. That's what gravity is for; I'll just turn the chassis over and shake it out like a pick in an acoustic.

You have not reached true amp builder status until you have done the chassis shake out. Or grabbed the red glowing hot end of your thermal wire stripper 2-3 times during a build adjusting the depth stop. (face palm)

That is one good-looking power supply board!

Thanks, I already want to redesign it. Add some solder pads for the V1-V3 B+ interconnect wires vs turrets. Re-think the footprint. This style amp makes it difficult to position the OT and power supply board so that the bolt hold patterns don't overlap. I already had the boards made and ran into issues when I did the chassis. I had to rotate the power supply board 90 degrees to clear the OT which put the interconnect wire points 90 degrees off of where I wanted them.

So typical of a 1st time build, I have a growing list of changes for amp #2.

lol, yeah, I'm ordering that PTS-30 today. I'm gonna try and avoid burning myself on it, thanks.

You will love it. Great also on stripping the tiny gauge guitar pickup wire like SD uses.

What kind of film caps are those French white ones -- Solen?

[Billy_Goat]

Looks like this is a Weber kit which is the same kit have. My build is also exhibiting low output. I've gotten a lot of amazing help provided in the forum, but so far unable to resolve.

Did the low output issue ever get resolved here? I've read through the thread, but I don't see a resolve. Did I miss that?

Cheers!

Solen, a not well known film and Tin foil cap within their product line.
