Thank you for prompt reply.
Of course I checked Japanese shops. But I could not find it.
Yes. I checked Mouser too.
But price is about 580 Japanese yen. 3,70€+S&H seems better.
I'm glad if you can send it via cheap airmail.
A few days ago, Filterx PCBs arrived. Me too, go to stereo.
Maybe I'll ask you about making it later.
