Dentron MLA 2500b pending payment

This was a NICE estate find, an old Dentron MLA 2500B, still in working order with the original pair of Eimac 8875's.
I warmed it up slowly, and ran the filaments for 10 hours before putting HV to the plate of the tube.
I tested the amp and with 50 watts drive from my IC-756 pro III ( metered on my autek WM-1 ) I got 1000 watts out on 10m, 15m, 20, and 80m, 1400+ on 40m, and 900+ on 160m.
So I ran it on 10 meter for the evening with 50 watts drive, peeking on ssb at just under 1KW just to assure there would be no issues, and I am confident this amp is good to go. This add is for the amp only without the tubes.
$400 + shipping
