MLA2500B Still works

Before returning the power attenuator to G4BVY I looked round the shack to see if anything else needed testing. Eyes fell upon the Dentron MLA2500. This was bought at a Weatherford hamfest for the sum of $100 and was restored as described at http://g4fre.com/mla2500b.htm  It was brought as checked baggage from the USA in mid2007 but has not been used since. It was turned on and left with heaters only for an hour. Then the EHT was turned on without incident. Trying it on 40m, but not pushing it too hard 60W in produced 700W of output, on 15m similar results. It still seems to work!
