First, thanks for all the info on this board, it has been extremely helpful.
I just received a pair of 5 Jr's made in 1987 according to the date on the back of the drivers. These speakers have the SL-2000 tweeters I believe as the visible leads on the plate are parallel to the floor.
One of these tweeters has lower output than the other, but it is still working, but not overly scratchy or anything. I swapped the speaker from left to right and sure enough it's the speaker, not the amp.
Would the lower output dictate the need for a tweeter replacement or should I wait until after I refurb the crossovers (as planned) before judgement?
