Do you mean that you wired the silicon in parallel with the selenium, rather than taking the selenium out of circuit?

That is what someone did on the RCA I am restoring right now.

Krikeys. That doesn't help with the problem of reverse leakage in the seleniums.

I did it years ago. It is just a single tie point now. One of the leads is no longer connected. Once the appropriate resistors come in I'll hide them and the silicon under the selenium. I hate to completely remove them as they do serve a visual purpose. I've never had one short to it's mounting screw that's why they are a single mounting tab now.
I'll check reverse leakage on the seleniums later today when I get a chance to sneak away from work.
