Ugly. It's like extreme showroom hotrod competitions...they look everywhere... I couldn't live knowing I disgraced my tubes and the GOT by using a PCB.

</sarcasm>

Sure, whatever.

Hello Digi01,

nice PCB! I build up a headphono amp from Headwize.com with the 6AS7 tube.
http://headwize.com/projects/showfil...aarde1_prj.htm

and it works pretty nice with my Sennheiser HD 600.
But my plans for the future are, to build up the ECC88 Pre you had posted!
Do you sell the PCB's?

Greetings Barossi

Hi,

Teflon boards anyone?

I still have to find a good sounding PCB mounted tube circuit that I couldn't improve simply by going P2P...

Besides, it's so much easier to repair, upgrade...no worries about lifting traces, hot spots, carbonized glasfibers and so on.

Nah, tubes = p2p.

Cheers,
