Hey guys, So I goofed on a repair and ended up with the wrong output transformer. Cut the leads and the reseller obviously won't taking it back. I might have recourse but I'm not sure -- I'm ramping up for a build I MIGHT be able to use it on. Can you guys please advise? The 40W transformer in hand is ClassicTone #40-18105 http://www.classictone.net/40-18105.html And the build I'm working up to will be 2x5881 cathode biased output section with a 430V B+. 5881 datasheet: http://www.tubeampdoctor.com/images/File/DATA SHEET 5881 Tung-Sol.pdf What do you guys think? I don't want to push it.
