I bought these from Government Surplus. Have no way of testing. Assume Used But still in original storeroom packing so may be new. Boxes say 400A, 500A and 800A but it says 4000, 5000 and 8000 on units. I don't know which is correct. Used selling on ebay for $250+ , new $3000+ each looking for $250 for the four.
May meet in Dartmouth. No guarantees, no returns.
