Thanks for bringing up this important question. Because others have asked the same, I've included the results of my listening tests as a addendum to the article. It appears directly above.

So how does it sound to you?

I understand JB Weld contains powdered steel which will give it some conductivity as well as extra strength. I measured it years ago and found that it is slightly conductive, so I thought I'd caution against an accidental unwanted problem. Of course, with an SCA-35 you would follow the procedure outlined by Dave. The fun thing about this hobby, though, is that you are free to devise your own solution to parts mounting and wiring as long as you follow the electrical diagram. The only exception to that might be to mount the new grid resistors directly on the tube sockets. Good luck with the project and enjoy the results! ---ART---

Hello Arthur,

Very interesting write-up with some good suggestions, ideas, and tips! I didn't know JB Weld was conductive!! I'm about to attempt this MOD on one of my 5 SCA-35s. I've been in touch with Dave Gillespie, but your write-up and your test results have further inspired me. I'm not 'up' to the level of you and Dave, either mentally or technically.....still got a LOT of learning to do! But, my 'enthusiasm' knows no bounds.....and I'm having a GREAT time finally doing some of the projects I've wanted to learn about since I was a kid (nearly 60 years ago). Anyway, thanks for your's a big help!! Tom - Wharf_Creek at Hotmail dot com.
