I’m looking for some ideas for grounding the base (shell) on some 813’s. They are recessed about an inch below the chassis. I’m guessing two “clips” 180 degrees apart would do. Doubt I would need finger stock, or maybe so?
Any suggestions or sources?  other than parting out four ART-13’s. BTW the application is HF, 10 M max.

Many Thanks

Ted,

The BC-610 I have that was converted to 813 finals has a two pieces of copper strap per tube screwed to the chassis and attached to the 813 bases with clamps.

Why do you want to ground the bases?

Ive used the proper twist lock sockets and submounted them whenever using 813's at RF; they are rather common on Fleabay.

Hi Steve:

It was suggested by a local ham and I believe its been addressed on the board before.
Just seems like good practice.
