Troubleshooting 5s analog radar scanner

[Miked]

Hi,
I wanted to document the successful repair of my radar.
1. Ohm'ed the cable and determined it was OK.
2. Troubleshot per the above procedure and with the SS=0, decided to dig into the core further.
3. On boat disassembly disclosed that one of the transformer thru [censored] leads on the modulator PCB ( R58057) had penetrated the insulation sheet and was shorting to the enclosure.
4. Located a new R58057 on ebay in Spain. Acquired at low cost partially due to fortuitous trip to Europe by a work colleague.
5. Reinforced insulation sheet, replaced modulator PCB - radar is now functioning per spec.
( that digital radar will have to wait...)
thanks,
