Title: Viking II R13 getting hot...? Post by: KC4HGH on March 05, 2006, 10:56:01 PM Just obtained the rig a few days ago & am going through it...previous owner says he plugged it in & turned it on, checking it out & R13 got hot, suggested replacing C10/11 & C12/13, but by the schematic, C9 is across it- could C9 possibly be going bad & causing this? I haven't put any power to it, just been spending some time cleaning it up & checking things beforehand.
Everything looks good physically...found where the previous owner replaced the power cord, but forgot to replace the blown caps C41, C42 & C53! Simple enough caps for the local electronics store.... Also, where's the preferred places for getting original or repro parts for the Viking II? I want this rig to be up & running correctly. Thanks! Bud, KC4HGH Title: Re: Viking II R13 getting hot...? Post by: ve6pg on March 06, 2006, 08:32:26 AM ...BUD..I REPLIED ON THE OTHER POSTING,BUT I RECOMEND REPLACING ALL CAPS,AND RESISTORS...IT WONT HURT TO USE THE HIGHEST VALUE OF CAPS,AND RESISTORS. IF A RESISTOR IS 1/2 WATT,GO HIGHER..1-2 WATTS..SAME WITH CAPS..HIGHER VOLTAGE WONT HURT..DO YOU HAVE THE 122 VFO?..THE PARTS IN THERE REQUIRE HIGHER RATINGS AS WELL..TIM....SK...
