Marantz 10 B Optocouplers.

170.213.131.100

Ok, several years ago, I replaced the original optocouplers by buying new ones.

I know have the same problem, again!

I've heard somewhere that someone uses parts from Mouser or Radio Shack to make them, but I've also heard someone came up with a design that uses LED's and phototransistors? to make them more reliable.

Anyone have details about this?

Thanks!!!
