Conversion from 6L6 to EL34

The early 6 knob protube 50 is a blatent copy of a JCM 800 2204. Circuit boards, chassis cutouts, transformers, etc.. all almost identical. Just like some of the 80's Marshalls this one came equiped for the USA market with 6L6's. We converted this one to EL34's for that classic Marshall crunch. While we were at it we replaced all the electrolytic caps with German F&T's and all the coupling caps with Sozo's. We even sourced some genuine NOS Mullard 34's for her! I do not think I have ever heard a better sounding amp.
