I am trying to find out what model and about what year, I think
it was late 70's, there was a single fifteen bass cabinet that had
a slot in it that was shapped like an UPSIDE DOWN champagne
glass and the 15 inch speaker was tilted in the bottom of the
cabinet. I wish to buy one even unloaded if someone has one.

I think it came with the B-100 solid state head?

Someone please enlighten me!

You probably need to check out the amp forum. Also look on e-bay or wikipedia to get more info. You never know what might just be a google away.

Good luck and I hope you get your amp.
