Before PMI became ADI Santa Clara there were two families of general purpose JFET amplifiers. I think the OP42/OP43 family is obsolete, at least I can't find our online datasheet and I've thrown away all my hard copies.

I suppose so, what piece of commercial gear used one of these (OP43)?

BTW, I spent a couple of days in Struer and met some nice young engineers at Ericcson really into analog and audio much more that over here these days.
