These are great little harp amps, single 6V6, oval 5 x 7 speaker. One of the best single ended harp amps for the buck. Forget vintage Fender anything, too pricy, this one is a definite buy. Even if the 5 x 7 needs recone, Neal's usually can do the job. I probably have one rebuilt here somewhere if needed. Good luck. Sonny Jr.
