I’m am overwhelmed by all who have contributed.
And quite proud too .

Now Andy, I know nothing about the Restek, so you will have to find someone else to help you tackle that one.
Lets get the Stasis purring properly first and bedded in over a few weeks of listening on those speakers of yours. Then we will check the bias /offset again, for maybe one last fine tune.
Everyone can learn a lot on this forum, so well done so far.

OK, once you get the Stasis running, you won't want another amp.
Congratulations... what a journey.. now you can scratch poorly.
Thanks mate , really though all the credit goes to Gary , Zen and others .
A fantastic thread / story with a perfect ending!
A short story about the faults would be useful.😉
What was the real problem?
Was a wrong wiring , a faulty component or a wrong placed component?

Is only protection the fuse on output? And with those nice speakers you have? A ssr speaker protection would not be a bad idea.
Burnt pcb’s , burnt resistors , at least 3 transistors on the output stage had failed, traces on pcb ruined, wiring to front display incorrect. And who knows what else ! All new internally now though 👍🏻
Yes that’s the next thing to seriously consider .
Looks like I have another project then 😩
My intentions are to use it in a second system for a month or two with some cheap speakers that I have .
I can’t risk a catastrophic failure of the amp AND the one off speakers.

There is no room in the Stasis chassis for a speaker protector, but yes, an external housing might be the go.
Is anyone aware of a commercial offering that might be available ready to go? Will save the member building one from scratch.
Good idea Andy, on starting out with cheap speakers. We will check the bias and DC offset after a month anyway.

Ebay have some relay based in finished in chassis, but do they work? There are some proven ones here on diyaudio, just needs chassis and soldering.
I bought one of ebay some time ago, relay based , it had a speaker fatal flaw,, the ground from amplifier had no pin, just the hot ones, a design flaw, and potentially a expensive one.

Yes I would be very wary of much of the stuff an ebay and aliexpress that is sourced from China.
I just thought maybe there was a good commercial product - but I can't find any.
Only option might be for Andy to assemble his own.

Xrkaudio, a member here has some "ready to run" solid state speaker protection boards, assembled on etsy.
It's a tested product. Just needs chassis, no relays that wear out, very low resistance, etc .
