My Golly JP,

That looks pretty good!
I am very pleased that my café doodlings have taken reality, thanks to XRK, and you, and a few others building. This does work very well, and I use this system on one of my commercial amps which has astonishing performance. I really like the sound quality of single ended circuit, they really are different to symmetrical topologies.

I´ve never paid extra charges; here online price calculation:
- mainboard 9EUR for batch of 30 (35µm, HAL, top and bottom silk)
- THT 2.3EUR (35µm, HAL, top silk)
- SMD standard 2.9EUR for batch of 30 (35µm, ENIG, top silk)
- IMS 4.6EUR (35µm, HAL, top silk)

Up to you, (with @AKSA permission? I´m carefully) for GB!
