Todd, I bet you will find the filament rheostat has a dead spot in part of its travel, where the brush rested for years until someone swapped the wires so that the OTHER part of the excursion now gets used.
People do this with spigots too, where off = on. OK, now that you've sampled the BC-610, when are you getting after the Collins 300-G ? It's not that it needs much... Paul/VJB __________________________________ Yahoo! FareChase: Search multiple travel sites in one click. http://farechase.yahoo.com
