Best transistor cross reference?
What the best way to cross reference a Sony transistor? I’ve been using Digikey for parts and the Sony part number from the service manual doesn’t show up on their site. Thanks.

What's the actual number on the transistor itself or where's it located in what model Sony? The service manual part number is most likely their in-house and not on DigiKey or Mouser

2SC1127 is the Sony part number. It’s in a Sony KV 1214 Trinitron. Thanks for your help.

If you get the Sam's for it Sam's often lists NTE equivalents. You don't want to use NTE equivalents in the sweep stages as some Sony's are picky about what parts will work in those stages, but for signal stages the NTE should be fine.

Sony has 2 numbers you can try.
First is the generic off the part ex. 2SC867-?? often marked C867-??. Actual Sony numbers are long ex. 1-###-###-## On a lot of parts it will have a partial number. A Sams or OEM manual helps. Sony IS very fussy about subs. Never sub any in the Hoz / HV semis especially before the 80's. 73 Zeno LFOD ! |

So I found an app called NTE quickcross. I used it to buy a replacement for the Sony 2SC1127 that I’m pretty sure is toast. Is that a reliable means to find replacement transistors? Thanks,

It’s for the Blue Chroma. In your opinion, is the NTE replacement ok for this application? Thanks so much.

It'll probably be fine. It's the horizontal stage that's usually picky about genuine Sony.

The trouble makers are the hoz output. Its called a gate controlled switch.
They are marked SG-### and are on a heat sink on the HV board. It takes nothing to blow one & some other parts. Finding the actual cause is sometimes imposable. When I was at Sony service they would often change the whole HV board to get one right. That was the mid 70's and almost nobody would touch one. Those that did charged $125 + parts sometimes the bill went over $200, a lot back then. My 76 Coupe DeVille was only about $8000 new IIRC ! And that was a REAL Caddy On your 2SC1127 you should be OK BUT on older sets you did have to use the OEM or the color didnt look right. They even had a bulletin on it. Cross that bridge if you come to it. 73 Zeno LFOD ! |
