The term "buck converter, not insulated" is an auto-transformer, one 240 volt winding, tapped at 120 volts, as the set was designed for 100/120 volt Japanese/US mains and is being used in 230/240 volt countries. |

SG sets we refused to do so I only did a few for some VERY good customers. Even when I worked for Sony I didnt do them. Other problem is Sony would use a totally different chassis in the same model ##. Had to go by the serial ## or SCC chassis ##. IIRC on the KV1710 some had a different supply using a second SG-613. What a dog & cost $$$$$$ to fix. BTW wernt they 2SC867 ? 73 Zeno LFOD ! |

I remember the chassis differences. I have several Sonys in my collection. I think I have a KV1710 that I think is going to be scrapped. I had a little grief with a SG-613 set. When repaired, it lasted around 15 months. When it failed again, I told the customer, "forget it"! |
