don't know if any of you have any of the iFR-1200-1500 series
I have Both a 1200 with spectrum and a 1500 with cell Test
I had forgot that I had the 1500 until moving things around, but it was Dead sort of after replacing the 7.5A fuse
the power supply in this had really bad Leaking Capacitors, so bad it ate thru the board Traces, and Componets
I replaced a but load of parts and had to clean off the PCB of smelly Crap
I ended up Replacing ALL of the Capacitors on all the plug in Boards, all Axial type
I didn't tamper with the Sealed Cavities
I like this Model because it will do Sweep, via front panel
Works Great now ! but I would like to see if I can adapt a N.O.S 95FB31 CRT in place of the original 95AB31 ( has Burns ) these are not available anymore anyplace
but I cant find any specs on the Factory 95AB31 or the N.O.S 95FB31 and its hard to see the pinout in the necks because of the Getter flashings
I only have pinout for the original 95AB31 in the Service manual, but no specs

Call this Radio Shack and ask to talk to Carl. He is there only on Saturdays and sometimes not.
