AWESOME!  Time owned: more than 12 months
I have been running the 110A for over two years now and awesome is the only way to describe it, Mine seems to be a little hot only needing about 75mW for 1500W out. I use it allot with my CE 20A through a 20dB pad and a 30dB pad with my "rice boxes" I run it in one of the glass front 19" cabinets built into a wall in the shack otherwize the noise would be intolerable, with the 400cps fan, I operate it with a homebrew remote from the operator desk. The only problem I have had was one time when I turned the unit off the high voltage control relay stuck and it was some time before I noticed that the high voltage was still on, about had a heart attack! knowing that those 4cx1500Bs would not be happy with the filament and bias removed, no big deal as the HVB-1 1/2 fuse blew, after prying the relay open and replacing the fuse all was well again!!

Great amplifier.  Time owned: more than 12 months
I agree with Mike W4MDL/W0YR about the RF-110.
I had the use of the RF-110 amp with the Harris
270-5 system which used the RF530 receiver and
the solidstate transceiver to drive the 110's.
Had 3 of them in operation. 1 of the amps had
the 8122 drivers, the other two had the 4cx250b
but all performed excellently. They will run at
the designed 1kw pep output level for day after
day, week after week for months or years.
Expensive if one has to replace the tubes but
they were primarily in government service so
the replacement costs not a factor. I might
add that the RF110/124 system was also a part
of the RF-131 system of which that exciter did
all modes including ISB.

Ray, W5XE
