Good evening,
I found the problem!
One ground trace is missing on the pcb, so pin 37 40 4143 46 49 52 were not grounded... Incredible nobody got the problem before 🤔
Anyway finally working 👍👍👍👍👍
Let's listen now 😊
Hope it helps

Great!You can use same config as 6n6p for 6n30.
Anyone interested if I organise a few pcbs for a 6H30 build?

This is not the Universal Tube Preamp PCB.
It is a tube buffer for 1et7040sa from this thread i guess.
