I made the jfets matcher.
@Robert would it be worth getting a PCB designed, that has this jfet matcher, some read points as a project so we can build a neat one?
There was that project for the R.G. Keen transistor tester too? in that particular case maybe including a 2.49K resistor prepopulated?
GCI NEW HM-2
Wanted to see if splitting the EQ would be good, I do love my Promethium. In my opinion I found that when playing with the GCI, where I preferred to have the high and mid was actually in line - so I guess I'll stick with my Promethium build.
I'd be lying if I said id given it a chance. I should probably sell it since I play headphones basically. Not a complaint on the device, and I don't really have the experience to say it's better or worse than another product.
