this 6″ speaker has the model name 6EV on it. I guess it’s Oxford from the 6EV. Oxford 8″ was 8EV-29 .
this Champ had some noise issue even without any input signal. it came from oxidation and fixed instantly with EML contact cleaner. I don’t use the infamous Dexoit anymore. the residue from Dexoit caused some problem on the vintage cloth pushback wires. EML is still the best for tube pins, input and output jacks and plugs, and potentiometers so far.
the filter caps were alive but the volume level was too law and didn’t sound like a Champ. this Champ sounds getting alive while the new caps are broken in already. the replacement is 33uf+10uf+10uf like my old Champ amps.
the texture was nice with GE black plate 575. but turned out it sounds great, I mean more like the Champ sound with RCA black long plate 12ax7 from late 50’s. I prefer 8 inch speakers but this 6 inch Oxford still sings
