Hey all,
I currently have a '67 Deluxe Reverb on the bench, so I decided to take some measurements of the output transformer and compare with two modern replacements. The Marvel Electronics is the standard 'Deluxe Reverb' replacement transformer you get from CE Distribution/Antique Electronics. It is wound on a plastic bobbin. The other two are paper layer wound. Here you go...
