I wish that I could suggest a supplier of the Telcom varistors - I=20 know they are still being used today because I see them inside=20 recently-manufactured equipment. Like I mentioned previously - these have a nice, soft knee which=20 makes them significantly less audible than the 5V part you are looking at. Actually, I just went to Digikey and pounded 'varistor' into the=20 search field. Then select '2 Vac' in the parametric search that comes up. 2Vac, 3.5Vdc, 100pF. $0.57 (Canadian) in singles, $0.19 in hundreds,=20 $0.078 in thousands. The only problem is that they are in 0201 package size (tiny). dwayne --=20 Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
