The June 95 QRPp newsletter has an article on the "73 special" using either
the IRF510 or the IRF511 so looks like they are close. You might want to
compare the schematic from that article with the amp you are building. I
used two little perf board pc's to make filters and
switched them with diodes - see the QRP Notebook #2 p 48. Works great. As
far as an attenuator see the Sept 94 QRPp for a W7EL amp with a simple 3 db
pad attenuator or see the book Solid State Design
page 64 for a similar design. Good luck om.
