Hello Phil,
Thanks. Looks like Amazon then. I like your web article about the real story of photodiode front ends. Reminds me of a morning where I sat in a big auditorium at our university. The professor showed the various configurations of a transistor on the overhead projector (those projectors without a PC...). When he came to the MOSFET and said that common base configuration would be utter nonsense I couldn't help it anymore. I burst into laughter and everybody looked at me. Embarrassing. I had just built an amp like that and it worked like a champ. And you could find similar amps in lots of the better commercial radios.
