IIRC, those are AR speakers (maybe AR-3A). Heath's speaker kits were OEM drivers in a cosmetically different enclosure (such as different grill cloth) and the purchaser assembled the crossover. I've got some Heath/Electro-voice speakers. Usually a perceived *dead* tweeter is actually corroded level control contacts, so a cleaning is warrented. Radio Shack sells Tuner Control Cleaner in a spray can which will be ideal for this. Spray into the round case opening where terminals are on control and rotate control several times. Invert to allow excess fluid and gunk to drain. Another common cause for a *dead* tweeter is failed crossover capacitors. Radio Shack also sells bi-polar electrolitic capacitors for speaker crossovers, you could get some close to the original uF value stated on cap and replace to check as older electrolitics tend to dry out over time. Usually the tweeters are fine, just the parts connected to them are no longer passing signal. I've done both repairs above to resurrect old speakers, sometimes leaving the RS caps in place and othertimes up-grading to modern film types. Paralleling more than one capacitor sums their values, and the RS *blue biscuts* metal-film caps offer a way to improve on the electrolitic cap if you decide to leave in.
