Original AR-11 crossover rebuild


Recommended Posts

Hello KAC Folks,

My first speaker purchase in the 70's was the AR-11, not long after I discovered the LaScala. I've loved both pairs ever since.

Recently I've embarked on my first crossover rebuild... I have a bit of soldering experience and used a meter to test speakers when I rebuilt four salvaged LaScalas. (loved the pre-fab crossovers from Bob Crites, RIP)

I'm more of a woodworker and have the cabinets already looking like new. I was told I would probably need to replace some (or all) of the capacitors and these are the assumed current component ratings (I see five capacitors so I'm not sure about this list - a later AR-11 version? -some in parallel?): 

One 10uF
One 40uF
One 50uF
One 72uF

I do see these numbers on a schematic I found online.

I'm hoping to get some advice on how to check the status of these parts and how to proceed. Photo attached. 

Also, included a photo of the plugs I cut to fill the screw holes... had 'em up on steel brackets with some added fastener security... living here in earthquake country!

Thanks for any help,

Mark

Have you tried classic speaker pages for advice? Lots of very knowledgeable AR people there.http://classicspeakerpages.net/.  There was an AR11B version also.

My brother had 10pi for decades (bought when they first came out) and now has a beautiful pair of 3a’s he restored. I had a nice pair of AR11’s for a while also although I was more of an Allison fan and owned a pair of Allison One for years and it is still one of my all time favorite speakers.

Good luck with your search.
