[Johnson] Grounding exciter / plate tune shafts on Johnson Valiant II

[Dave Maples]

All: I have after about 3 years started working over my Valiant II.  I
thought I had read somewhere that a source of chirp (as well as heat) was
the ungrounded capacitor shafts on the exciter and plate tuning capacitors
(the capacitors go to ground through the shafts and the bushings on the
front panel).  My understanding was that grounding those shafts back at the
capacitors themselves would result in much better performance.  Anyone here
comment on that?

Thanks,
