I am selling this for my father-in-law. Bought it years ago with a set of Celestion SL 6 SI speakers. I think he paid close to $3,000 for the setup. Anyway, mostly just trying to sell the amp for him unless you are interested in the speakers as well.

There are some specs on it.
Here are some reviews:

The unit seems to work perfectly. I don't know a lot about tube amps, but I know this one is a little unique in that it has volume control and inputs, so it negates the need for a preamp. Sounds great to me and everything lights up and seems to function.
Asking $1100
