Oops, nevermind, still have unclaimed boards, I was miscalculating. Sorry.
And boards shipped to me. If anyone who contributed didn’t get BOM&Notes, let me know.

All US shipped boards should have arrived. If anyone's hasn't let me know. The Internationals are probably another week or so.
My apologies, I forgot two capacitors in the BOM for the PVI cell power. This is not a special spot. I added two of these to the BOMs. 16v 680-1000uf is fine.
Also the PVI boards are marked 33uf, but BOM has 56uf because it was a better option.
And yes there are still some boards from this GB.

Paul shared me with these. He's just testing it on some old speaker but said it sounds really good.
Just a quick note that you do not need a heat sink anywhere near what I am using. I played the amp for over half an hour and it did not even start to get warm. The LED is hot so do not touch it ( yes I could not resist) but the heat quickly dissipates.
The build was very relaxing to do and I really enjoyed it.
I have not adjusted the DC trim and the speaker I am using is "meh". Comparing Jeremy's 7297 amp and this 7293 on the same "meh" speaker, the 7293 is, to my ears, just on another level over the 7297. When I made the 7297 I first noticed that I was able to hear separate instruments rather than "music". With the 7293 I can now hear the "character" of the instruments. As an example I can differentiate between two guitars rather than hear two guitars. In one song a cutting board is used in the percussion and I can now recognize the cutting board. Once I get both boards up and running I will hook them up to my X-LS and once I finish the kuartlotrons I will hook them up to my GR Research Wedgies and 12" dual servo amps.
I originally bought the boards to support Jeremy as I really liked his 7297. I had no idea, or had any expectations that his 7293 would sound this much better, even on a "meh" speaker. I cannot wait to get this amp hooked up to the Wedgies and servo amps.

Thanks for the impressions, Paul.
Looking forward to building this once my 7297 build is complete, and will be pairing them with Wedgies as well.

I am hoping to build pair of these. This will be my first time building an amp. I also have GR Research speakers. The Super 7s.
Nice speakers....this is a really nice build and I am confident that you will enjoy it. Jeremy gives incredible support and walked me through several builds.

Looking forward to your impressions with the GRs and servo subs. I’m planning on building some wedgies or NX Oticas and am considering matching them with the 7293 so let us know how they sound when you give them a listen. Thanks!
Thanks, I imagine that I will have a lot of questions once I get all the parts in. Should be fun!
