A 3-1000Z runs around 65 ohms. Some input network tweaking will be necessary with a transistorized driver. 73; /archives//html/Amps/2009-07/msg00085.html (7,812 bytes)

I was actually going to suggest that he checks that all 3 grid pins on the socket are grounded.

The degradation in the amplification factor is so slight as to be negligible. Don't forget that in the GG configuration the grid its; /archives//html/Amps/2009-07/msg00094.html (10,381 bytes)
