I've always just used feed-thru capacitors for a permanent link and an
amphenol-type multiconnector for removable panels and to a separate power
supply. If i use a multiconnector I use a .01 bypass capacitor as you suggest.
I don't recall any problems as a result of this

Subject: [Amps] bypassing control leads
My homebrew amp has 3 compartments - the RF compartment, an under-chassis
compartment for the input and control circuitry, and a front subpanel area for
metering and control knobs and switches.
What is the preferred method for routing control leads from the under-chassis
compartment out through the subpanel to the various meters/knobs/switches. A
grommetted hole with bypass caps on the inside? Feed-thru caps?
The Orr handbook (23rd ed. p.12-10) has a comparison diagram of various lead
filtering setups. The most bang-for-buck appearing to be a single .01uF
Sprague hi-pass feedthru cap.
