There was one presented in QST some years ago. I have a photo somewhere. It
used 25 or 30 each 1625's and a dozen TV power transformers. It was fully
broad band to 50 ohm output on any band. No tuning of any kind and no
filtering necessary. Was pure Class A.. Of course the cost was somewhat less
than 30 to 80 thousand dollars.. Mike
