Thanks again, CeeVee. Probably I will just do point to point wiring. Sometimes it sounds better than PCB. The CAD file Vincent (Thanks, too!) posted is definitely helpful and the price of Front Panel Express is fairly decent. I am still pondering on which route to take.
Ok, as promised here is a picture of my Type 1 display.
Almost all is well, discovered yesterday that the brightness control is not working, although the contrast is....
This is clear from the picture, the background rectangles are way too visible.
Just a little bug, i hope.

Does voltage on pin 12 of AD8402 (wrt ground) varies when you change brightness ?
(Limiting resistors for the pot are 12K7 and 3K92 n my case, instead of 12K and 4K7 as written on pcb)

Hi Cheff,
12k1 and 3k3 works for me....just because i had them lying around hehe.
........i confused the values with Type 2 display 🙁
all is well and lovely, thank you!

Those PCB are original CheffDeGaar's own UGS, ultraFlat design 😉
So there will a second unit in the world 😛
The PCB GB vmoreau did is for a 2units enclosure design.

The board was made for me by the same company that made de GB boards, found them through the discussions with Pavel Dudek......his amplifiers are built with some of the most beautifull boards i have seen.
May I ask some very stupid questions here.
1) Can I just don't use sub pcb, input trigger board and amp trigger board. Is it still working?
2) When flashing the micro-controller board, do we need to connect the power supply together and power it up. Or can we just connect the micro-controller pcb to the program pcb and plug it to parallel port.
Thanks in advance.
