I have inherited a set of really nice 846B valencia's from the in laws. They gifted them to me before I would inherit them haha. Cabinets in great shape, and even the front screens are present and in good shape.
The high frequency horn on one was not working so I did my web research and found Great Plains Audio and dutifully sent both of the grapefruit sized business ends of the horns to Bill for new diaphragms and remagnetizing.
Now it comes to crossovers. I learned that the crossover capacitors are likely feeling their age and need replacing. A little background,...I am a licensed aircraft mechanic, well versed in mechanical doings,...so I am fully capable of identifying and resoldering in two capacitors. Problem is,...when I do a search for the capacitors I get a zillion,...and I do mean a zillion, hits for capacitors with those values. Bill at GPA said to be sure to get capacitors with the same general size as the old ones in order to carry the intended power. Makes sense, as you can get capacitors with the right electrical value that are tiny, and that would not be good. So,....I wanted to find something that would work for my situation.
When I do forum searches I get threads like "I recapped the crossovers", and "just replace the capacitors", and "got some capacitors online and put them in."
All this is well and good,...but what I am hunting is specific stock numbers, and a specific company, and a specific web site where I can get the two specific capacitors I need to get.
I am not wanting to get into building new crossovers, improving the crossovers, or showing my audio expertise,...I have none. Just wanting to do what's right to get these great old speakers safely playing again for another 40 years. Hopefully someone has specific info I need, and where to get them. Or maybe someone here sells exactly what I need?
Specs are:
N800-8K Network
8 ohms
846-B
Large capacitor reads:
NP
CALLINS 7239
9-CXPSD21-75NPS
21uF-75V NP
Small capacitor reads:
NP
CALLINS 72??
8-CXPSD8-75NPS
8uF-75V NP
Thanks guys.
