It's been about 6 months since Part 1 of this series was printed so I thought it would be a good time to give an update on the Fender amp research that I am doing along with Devin Riebe and Greg Huntington.
Non-Schumacher transformers – It’s been universally accepted that Fender only used Schumacher transformers on amps made in the 1960s and 1970s.
Combined with what we saw with dating a tweed Fender Champ by the tube chart and speaker code, I’m feeling pretty good that all of the various dating methods point to early 1959 for my amp.
I wish I could say that I figured all this out on my own.
While doing research on Fender amps in general, and the Champ in particular, I came across the most amazing series of articles by Greg Gagliano on the subject. If you have any interest in vintage Fender tube amps, without question you’ve got to read them all.
The process that went into figuring all of this stuff out over 6 years and countless owners of vintage Fender amps is hands down an amazing story.
