Quite a rare item in the UK.
These have been a bit of a pain for me as 1 transformer was broken on purchase,and the 2nd went as soon as the other one was sorted.
Both transformers were sourced and fitted by Henry,top radio man? at the cost of around £450 the pair.
They now only work in class A which is all i wanted them for originally.
There is a tiny amount of hum through my speakers,though being efficient,i guess this makes it louder than normal speakers.
Output is about 25wpc in class A
Soundwise,these are superb.
Condition is about as good as i think you’ll find.
Sold.
Pick up from Devon,or can post for £15.00
