When I was a little boy, around 8, I must have been so intrigued by the looks of the wooden glass top speakers at my aunt and uncle's place that 35 years later I could identify them by doing an image search for glass top speakers on google. I hoped they were l65's but I wasn't sure. Anyway my aunt and uncle both passed away and i asked my cousins if they still had those speakers. And they did! And guess what ... I could come by and take them! Oh joy when I found out they were the L65's I had hoped for. Me so happy!
The state is fair, the cloth is stained with mold, the veneer is relatively ok, the midtone and tweeters are like new and the 122 woofer just needs a new foam. My cousin told me that something was wrong with one of the speakers but didn't now what.
I'm now in the state that I have the new foams for the woofers, the cabinets are cleaned and polished.
Before I put everything back together I would like to rebuild the crossover network, since the caps are 40 years old.
I bought some German MKT-A audio caps from visaton, nothing fancy but good quality.
I have some questions:
- I'd like to clean the potmeters, as this might be the cause of the earlier mentioned problem. There is a JBL sticker on top op the pots that I'd rather not remove. Can i clean these pots from the inside and how would i do that?
- Is it a good idea to replace the caps on the crossover?
- Some of the original values are not made anymore so this is what i got:
C1: 15uF (13,5 on the datasheet, 14 on the cap)
C2: 1,5uF (same as the original value)
C3: 4,7uF (original value is 4uF)
Is that ok? What will that do with the sound?
Kind regards from belgium.
