My 67 BF Deluxe Reverb's tube chart is wrong it's for a Deluxe. The guy I got it from got in in the mid to early 70s. Pretty sure that's the tube chart it came with. I'd heard before this that Fenders tube charts were often wrong.
I take it it's working OK ? Then I wouldn't worry about it.
I would however get a three prong plug on it.
