FS: Marconi IFR Aeroflex 2025 synthesized RF signal generator 2.51GHz, opt 04,12

[volvo_nut_v70]

IFR 2025 with options 4, 12, nice clean unit. It has all the feet and handles.

I have sourced the various service passwords for the unit and they are attached.

Checked the power supply and it is okay.

This generator gives a  Error 502-N Fractional loop error. From what I have found out, this error is a symptom of SMD Electrolytic cap failure on the RF Deck.
These generators do have SMD caps that fail so my best guess is a SMD tantalum or electrolytic cap is faulty on the RF deck.
