Layout question 50w Dumble

Post by Oddvar R »

Hi. I am about to finish my 50w Dumble, but I am a bit uncertain where the grounding of the preamp jack is going, or is it just a shield?

You are referring to the preamp out jack? Both of the loop jacks are grounded to the chassis through their bushings.

The right way to do that would be to isolate the preamp out jack from the chassis, and carry the shield ground all the way back to the level pot.
