PP Guitar Amplifier Head

"Dear team at Thermionic Lab,

I am finished with my build and happy to say that everything is up and running, ans most importantly, sounds amazing! Thank you very much again for the communication, guidance and support.

Attached are a few pictures of my 2 channel guitar amplifier based on a pair of push pull KT77 with 5 12ax7 in the preamp. I think it looks neat - the color changes depending on the active channel.

Best regards
Nicolas"
