Alright, can't wait to read the 7000 posts in the next 3 years.

It's kind of confusing...

There has been a long running thread on here where people discussed, reverse engineered, and iirc made PCBs to build both the KSA50 and the KSA100... both of which I've heard extensively over a long period of time and would not want to own or listen to - but that's only my preference.

Afaik, it's essentially the same circuit as the Bryston amps, but biased for class A and with many more output devices plus a much larger supply and fancy heavy aluminum case...

But whatever... are you saying you are going to be making a commercial product? Offering PCBs to Diy'ers??

Where are you located? In China?

If you are selling - you want to put it in the Vendor topic & section.

Yes, I was in China, PCB free to you, but I am not responsible for the shipping.

Trying to understand - you have a *single* - one - PCB to give free if the person pays for the shipping??

OR, you are making or selling many PCBs??
