I've been offered a pair of early build (1981-2) one-owner 509s in good working order. The amps show minor signs of use, commensurate with age, but appear to work just fine. The original owner's handbook is included along with a new set of output valves.
Can't find much sales history for these amps on-line, so can 'fishers suggest a fair price?
