Anyone know Vintage Ampeg Amps?

okay, i think i've got a vintage AMPEG BT-15 FLIPTOP, but i cant find too much info on the model, i was looking to find out how much they are worth, and if they are worth putting money into...it could probably need new tubes, but i dont know how to check....im just guessign that cuz its old as hell....
anyhelp would be great.
thanks.

there are several different variants of the b-15. The original ones are worth a bit in good shape, but the later ones aren't really worth much. They are kickass amps, though. The little glowing Ampeg plate is super- cool.
I don't really know where you can get specific info on your unit, though. I would say to just keep trying as there are lots of people out there who get huge hard- ons over Ampeg amps.

I could kick myself for not buying one of those 22 years ago. My mom talked me into getting a "brand new" Peavey instead. That piece of shit didn't last 6 months.

What case is it in? Is it brown or black? Does it have the glowing etched glass piece?

Ampeg
you can find out a bunch of info here---Ampeg is tricky because they have lots of vintage stuff...and then periods of ownership where their gear was not quite as well made...good luck with the search

Hang onto it. Old Ampeg Flip-tops are amazing, even if you are only going to use it as a tube preamp for DI purposes.

how do you think it would sound running into a marshall head or vice versa? i'd like to use it somehow....
