These were bought as a stopgap while my Sugden was away for a service but have remained in my main system since. The class A amps are in perfect working order and to my ears sound terrific. They are built like tanks, the power amp itself weighs in at 26kg’s. Appearance wise, they are not perfect, there are no dings or dents, but there are a few light brush marks on the power amp casing. I did toy with getting the rear and top cases resprayed and keeping them but an impending project means they have to go. Unfortunately there are no original boxes so they will be pick up only from central Scotland and. Together, they are very impressive, but I’d be happy to split if necessary.
looking for £350 for them both.
