RE: Tube emitting tone

Posted by pictureguy on October 3, 2021 at 14:42:47:

For tubes OTHER than ouput, which I suspect tend to run hotter, you don't need a brand name.

Find a place that sells Orings.....online will do.

Buy a high-temp o-ring. Red Silicon is goo to hotter than low level tubes will get......

you'll need diameter.....which can be gotten with a PIECE OF STRING and a ruler......easy calcuation involving PI.

I linked a SQUARE cross section ring, which should have MORE bearing area on the tube.
It comes in BUNA and SILICON......The Silicon is GOOD to over 400f.......
