I got some speakers from my Dad recently. They're CS-77s from the early 70's. From what I've read, they're not top-of-the line, but they're pretty nice.
I remember them fondly from my childhood. I didn't use them much for a few months while I tried to figure out what to do with them. I finally decided to keep them, cleaned them up, had the tweeters re-foamed and turned 'em on.
One sounded normal (pretty nice to me) and the other had some issues (really quiet).
I changed wires and terminals to verify the speaker and it was....
I got out the voltmeter and found one the of caps on the crossover basically shorted (1 ohm).
The individual speakers all show a resistance of 6.5- 7.5 ohms - so I assume they're ok.
Is it still possible to replace this capacitor with one of the same size and shape? I'd rather not have to change the crossover board configuration.
Should I replace all of the capacitors - given the age of this crossover?
If yes, then I likely should replace all of the capacitors for the other speaker too?
I think I've got the schematic pretty close, but I'm not an expert - RSW=rotary switch - which can select between settings Decrease, Normal and Increase for the HIGH and MID Ranges.
Any advice is welcome.
