Today as we annualed my 65E we discovered no Port or Tail Strobe except a single flash on system power down. The Starboard worked initially and then joined the others. Suspect common cause. The single, fuselage mounted, Whelen Power Supply is an A413A HDA-DF-14. Whelen says they no longer make or repair this unit. They suggest replace with a CF-14. Looks like close to a thousand $ to replace. Probably just Capacitors. Any suggestions on someone to rebuild/repair. A type and source for capacitors. Or a source for a servicable unit.
