Yaesu transceiver blowing fuses ? FT101/102 & FT901/902
AVOID BLOWING THE 6146 FINALS OR EVEN THE MAIN TRANSFORMER - SEE PHOTO OF VALVE 6146B - THIS IS THE RESULT OF A COMMON FAULT WHERE THE C1701 CAPACITOR ON THE PA PCB BOARD STARTS TO LEAK WITH AGE OR EVEN SHORT CIRCUIT. IN MY CASE ON MY FT 902DM THE 3A MAIN FUSE BLEW, BUT BEFORE THAT THE PA VALVE MELTED (see photo) THE CAPACITOR LOOKED PERFECT BUT IT WAS READING 204 OHMS !!! AFTER REPLACING IT WITH A NEW 100PF CAPACITOR RATED AT 6000V THE RIG IS PERFECT. PROTECT YOUR RIG NOW - FIT THE REPLACEMENT (Comes with instructions and illustrations from the Yaesu Service Manual on how to locate this elusive component) FT101/102/901/902
PLEASE SPECIFY YOU RIG TYPE TO ENABLE ME TO SUPPLY THE CORRECT VALUE CAPACITOR AND SCHEMATIC DIAGRAM FOR YOUR TRANSCEIVER
