Hi, my name is Marek. I’m 49yo physician from Krakow, Poland. I’m very keen on your projects, many thx for your job!  Behind me is DTQWT-12.  Now it plays with my DIY 15 Watt SE with 6C33C tubes, project by Erno Borbelly. Together they sound wonderfull. But I need to make another step, it never ends!. 
Now I’m working on your preamp WOT 6N6P with DAC-END by Andrea Ciuffoli.  A firend of me makes perfect trafos and I asked him for interstage ones.
Sincerely Marek.  
I’m ‚black'. Andrew, white, helped me a lot with 6C33C amplifier. .
