Hi, I was wondering if anyone knows if it's possible to convert a Traynor YCV40 to an YCV50BLUE, and if so, how hard that would be? I already have an YCV40, but I like the tone of the EL34-powered 50 more. They are pretty much impossible to get over here, though, and as a mere college student I'd financially prefer it if I could simply mod the 40. The YCV50 is based on the 40 and the schematics (YCV40 here, YCV50 here) look very similar with only minor differences, but I'm not an expert, so I'd really appreciate it if someone more knowledgeable could chime in. Thanks!
