I just remembered I have a Peavey KB300 amp with a Black Widow speaker stored in my band room. I bought two in the late eighties, but they weigh about 95 lbs apiece. I wonder if the tone stacks up at all with modern amps. I loaned it to the band 10 yrs ago for visiting players, and forgot how it sounds. They sounded wonderful then, but so did my old D-50 KB.
Great amp for its time but most guys forgo keyboard amps these days in favor of powered PA type speakers. Much better sound quality, more power, lighter, and you can put them up on stands.
I had two similar amps made by Crate, KX220s. They were great but once I got my JBL's they were gone.
