? However, there is nary a clue in either on how to go about building
the broadband Class AB1 neutralization / grid input circuitry. This
info is on my Web site. A grid supply and a screen supply is there too.
- BTW, Bill, if you need a 450 ohm grid term. R for a "tetrode with
handles", I found some in the attic yesterday. Also, an ideal grid
roller coil is currently available from Fair Radio Sales for only ten
dollars. It was mfg. by Collins for one of their ant. tuners.
