I send to you a picture of my 807 "Oldschool" tube amp. It's Homebrew Audio made in Germany.
In the first stage I used a EBC91 (6AV6), followed by an Russian 6H8C (6SN7) that works in SRPP configuration. Next is the 807 tube in SE. A special gimmick is the EM83 magic eye with to sections, one for each channel.
