[TenTec] Omni 6 sidetone.

[Mike]

Now I've got my Omni 6 in action again, I'd like to do something to either
cure, or alleviate, the clicky/thumpy sidetone which has always been a
feature of my Omni 6, from new.
Thump/Click problem exists even with power-out set to minimum, at all
settings of sidetone level & with both the internal & external keyer, so
guess its audio-related rather than RF leakage.
Anyone on the list had this problem?
Any fixes?
