These were given to me by a family friend about a year ago, I don't know an awful lot about them due to google not having much information about them.
Quote about SAI from a previous post, by Lee-7:
SAI (Sound Advice Installations) were based in Standish/Coppull and Preston back in the late 60's and 70's producing cabs & amps that were based mainly on Vox & Marshall of that period. I think they were all class A valve amplification, of a very high standard and a make of amp you see very little of these days.
*100W (Each)
*Imp: 8
*From what i have found out, It's safe to say that they are somewhat rare.
- Unfortunately i don't know much else about them.
They are both in great condition.
I would be looking for £200 for each.
