Title: WG 9200 neckboard transistor replacement
Post by: mclovin on June 25, 2017, 12:27:05 am

Hello all, I was having color issues with a wg9200, so I swapped the neckboard with a known good working one and it fixed the problem. So I might as well try to fix the spare neckboard. My question is the 3 transistors say c3503-e. Can anyone recommend where I can find these and if there is another equalivent model that I could also use? I would like to order a few l. Thanks

Look for 2SC3503.

Great, I find some or equal on mouser. What about the large white resistors, should they also be replaced?

resistors are really unlikely to be broken.

i've had far more video amp IC's on the neckboard go than bad resistors.

Ordered the transistors from mouser and all is good.
