Rob,

Sorry to bring this back from the dead, but do you have a part number for the transistor that s&s replaced in your DC DC converter? The transistor in mine was so badly burned that I couldn't read the numbers off of it, and the converter PC board does not have a scematic in the 7909 service manual.

Thanks,

Ben H.
