Was Dan Rupe the engineer? My memory is so terrible. I remember Harold Greenburg and Ken Copper. A few others have written and I remember them but one of these days you'll have to give me the staff list as you remember it. I discovered spray Lysol early in my career and ruined many a mike with the spray. Those RE-20's were indestructable but even so I eventually just sprayed the paper towel and did a good wipe-down. Solved the problem although inhaling all those Lysol fumes has caused my memory to go hay-wire from the brain damage.
