My father no longer needs his ESL63's. They date from the 80's, not serviced, sound ok, no boxes and located in the far SW of Cornwall. I've seen tidy serviced pairs hang around here for ages at very reasonable prices compared to service costs. They are not for me, and I'm at a loss as to what to do with them short of ebay with ultra low start price, any better suggestions welcome. No sign of arcing when played in the dark, but I'm no expert on what to look for in terms of faults on these.
