it worked as recently as june 29th, as i was able to play the tears for fears record on that date. that would indicate that the tweeter was damaged sometime after that.
i remember turning it on briefly on the 1st and i do recall a short in the system that i traced to a faulty rca wire and replaced.
was that the cause of my headache? i'll note i smelled a strong burning smell.
whatever the cause, these speakers are not usable for the foreseeable future and i'm going to have to plan around it. i now have a vintage burnt out celestion tweeter, and a tweeter that doesn't seem to be labelled (or lost it's label) that has no coil.
given that they're both blown, i should just buy two new tweeters, in a matching set, and plug them in.
