An update for all. I ordered a couple of terminal strips to replace the 8 lug one that was there. It made it look much neater. It took a while to get it which accounts for the delay in posting.

After I noticed that it did motorboat but if I moved the wire that went to the 6Q7 grip cap it would stop. I moved it to behind the terminal strips and success…no more motorboating!

I want to thank all the members that assisted me and I look forward to my next project.

So, that says something for shielded grid cap wires. I've seen it before but didn't realize how effective it is. Great find, Bob.
