I always used a pencil eraser, worked great. On old Stromberg Carlson Switch gear to clean the contacts I used a $100 bill. Not much grease on them. Hi hi...

Often the oxidation is such that it prevents a very low level signal from passing. The solution for many instances is simply to clean connectors. My approach is to use a Q-Tip, apply your favorite contact cleaner to the Q-Tip, unplug one connector at a time, and scrub the male pins. Then exercise the connector in and out of the jack or plug to wipe the female socket. Then move on to another connector, doing the same. And for gosh sake, NEVER NEVER spray anything into the radio, a socket or a connector. You'll regret ever doing that for a long long time. 73 Bob, K4TAX On 7/10/2019 12:14 PM, Grant Youngman wrote: > i have never had a problem with TMP cables themselves.
