Hello, new to the forum here and in need of some advice. We have a pair of L65 A's (122A, LE5-5, 077) in beautiful condition. We have owned them for a couple months now and love them.
I am wondering about the condition of the capacitors. I know they are 25 or more years old.
Should i just go ahead and replace them? and if so, what type of modern caps would you use?
Should I only replace C1, C2 & C3 as shown here, http://manuals.harman.com/JBL/HOM/Te...Jubal%20ts.pdf (http://manuals.harman.com/JBL/HOM/Technical%20Sheet/L65A%20Jubal%20ts.pdf)
Do I keep the exact same values? I don't really want to mod them, lets just say refresh to an original state.
Are there other components that may need attention?
someone had mentioned "air coils" in a previous thread.
I know I can do the work, I just need to know what components I should replace. And with what. And finally.... where to buy them.
does anyone have an actual pic of the crossover? i haven't dismantled these yet. I did pull a woofer and a mid to check driver #s when i first got them home.
We plan on keeping these and taking very good care of them.
this is my first post but i have been following/catching up on the 4345 DIY with great interest. I was about 12 when my big brother walked me into a pro audio store where the guys there were playing around with a set of these. I remember they were giggling like kids in a candy store. Ive been wanting that sound ever since. I really want a 4-way monitor bad. I might try a 4341 build, or get lucky enough to purchase a set.
Thanks in advance to any and all
