Hi all,
    I'm presently working on my first build, a 5E3 using a Ceriatone head chassis.
These chassis are powder coated.  Do I need to remove the coating for anything other than my ground points? (I’m using one ground at the transformer and a buss grounded at the second filter cap for everything else) Specifically, do I need to remove the coating for the pots, switches, input/output jacks etc.? The amp is nearing completion and I'm getting worried that I've made a mistake not removing the powder coating, especially at the pots. Thanks for any help.

Awsome. This is what i've done. The speaker output jacks, mains ground, power transformer grounds and first filter cap/power tube cathode resister & cap are all grounded at the corner of the power transformer. The volume/ tone control grounds I fed back to the input jacks and have just one ground off of the input jack attached to the first point on my ground buss. All circuit board grounds are attached further along the buss and the buss is terminated/attached to the chassis at the second filter cap. Thanks for the help, I feel much more confident about this now!
