these were recapped a few years ago, but only have a few hours on them. these originally powered my polk audio 1.2tl speakers, with a ground strap. I moved those downstairs and I have been to scared to use these on my martin Logan request's. I know they have a very low imp. and I don't want to overwork the amps. at the time of the recap, I spent ,800 on 16 nos tubes for these, with only a few hours they should all test at nos levels still. these can be switched to stereo amps at 100x100ea. but they are still stock. they are rated at 200w ea. but they do not make it to that, they clip at about 191w if I remember right, was tested after the cap service on the techs scope. still great amps with a lot of power. these are heavy at around 45lbs ea. so they will have to ship in 2 boxes with tubes removed. I also have bases with feet (not pictured) just the 3 can caps on top of ea. were over 0 plus a little over 0 for the service, so it was a little over ,400 for the work and tubes, so I will not entertain lowball offers, these amps usually sell for k with no tubes in them. shipping listed is to the lower 48 only.
