Toeknee Posted August 29, 2009 Share Posted August 29, 2009 I purchased a pair of Heresy's off e-bay they are from 1980 (according to date code U) I hooked them up to try and they did not sound right. So I recapped both 2uF caps on both networks and then took Resistance readings the woofers were 07.1 and 07.0 ohms (K-22-E) the squakers 10.1 and 11.5 (K-55-V) and the tweeters 05.6 and 0 on the bad one (K-77-M) Do the rest of the values look OK. Anyway looking to buy a single K-77-M or equivelent if anyone has one. Thanks Tony Quote Link to comment Share on other sites More sharing options...
DizRotus Posted August 29, 2009 Share Posted August 29, 2009 You probably just need a new diaphragm. Contact Bob Crites, BEC on this forum. He can sell you one of repair your existing K77. Quote Link to comment Share on other sites More sharing options...
