Hi Juan,
That Green amp looks interesting. Kind of a Spooky front end with a super pair in the VAS. I want to try that one now. I really need to build a chassis for my Arc welder boards. It's a shame to have them just sitting on a shelf. This quarantine time is a good time to get back in the studio and build some amps.

there is 16 gauge galvanize sheet metal at home that I want to try build one for other project but I decide to just order chassis since the project I have is been sitting around for months I need to complete finally Terry a complete project is gonna be fulfill totally is about time lol great day Terry stay safe at home 🙂

Nice work Juan. Nice to see the power supply we designed being put to good use.
I get my final piece of my case back from anodizing tomorrow. Some parts came back from power coating the other day. Good luck with the rest of your build. Stay safe. [emoji40]
All in one PCB idea
hi I just got this idea I was thinking man too many board where do I placer them inside the chassis and then this idea come out is crazy but I think with 80mm standoff I can make it work I call this one "All in one PCB" a simple 12V DC circuit to turn one the soft star and the speaker protection that Mr. ST and I design all on the same PCB this I think will make the connection even cleaner I'm glad that I save the dimensions of the power supply the outline is accurate yes and also the ground loop breaker too from Elliott's designs too 🙂

I think its a great idea.
Just some thoughts....
I would place the speaker relays closer to the edge of the PCB so the tracks are shorter.
Replace the relays with FETs.
You would need two earth lifts for stereo etc

good thinking, but FET's instead of relays? I never seen that before do you have the circuit?
There are many threads on this subject e.g.
SSR for speaker protection?
Look at Post 95 for ideas.
Also it might be best to have the speaker protection board separate, near the power amplifier output and your " control" board near the mains inlet. Just suggesting.

hi Harry3 really interesting SSR circuit I like the idea of placing the small PCB at the back of the chassis that is a clever idea even I found that gerbers are share really nice I'm gonna keep reading and see what I can do thank you for your suggestion agree the traces are too long I will see what I can do maybe I don't need to do it because of this SSR that goes at the back of the chassis
Hi guys, if you have ever wondered how these amplifiers actually work and would like to watch a few educational videos which may hep you design your own one day. Check out this channel on YouTube SW Audio YouTube Channel

I Hope this is an Acceptable Practice but ...
Hello all,
I am cleaning out my parts closet. I have lots of goodies that I won't be using and thought that I would share them with my fellow inmates on this forum. I've got Slewmaster PCBs and lots of power output devices. I don't expect them to last long. I invite you to stop buy and check them out.

I’ve been laying low lately (work and health issues) but wanted to use some parts and materials I had on hand.

Looks like you've trading in the lumber for aluminum. Is that going to be a 4 channel monster?
