Johnson Ranger Problem

I own two Johnson Rangers, both of which have been totally
restored and operate perfectly. However, one of the units
has always had a problem which concerns me. The problem is
arcing at the "OPERATE" switch whenever one is going in or
coming out of the "PHONE" and "CW" positions - in other
words, whenever B+ voltage is applied to the tubes.

This "spitting", which can be heard (and seen when it is
dark), always occurred with the one Ranger, even after it
was totally restored. However, the other unit is and always
has been absolutely void of this problem. Both units have
the CW  Keyer board and PTT modifications - and are
identical, as best I can tell, in every way.

Does anyone have anything to suggest with respect to the
cause of this arcing and what might be done to extinguish
