SX-117 Power transformer Voltage
开云体育Hello Wolfgang, From the schematic and the “normal” voltages chart in the SX-117 manual, the primary +B voltage at C117B looks to be 200V. Which means a transformer HV secondary of 280Vct (140-0-140). There is also a replacement transformer specified in the attached document, but the secondary voltage rating seems to high, IMHO. ? 73, Jacques, VE2JFE in Montreal ? Hello, I am restoring a SX-117. A former owner replaced the original transformer by a transformer with a primary voltage of 220 Volt. The secondary voltage of this transformer is much too high. I would like to know if there is any info on the secondary voltage of the original transformer as I am looking for getting a replacement. 73s Wolfgang dk7cy |
