[Amps] Band switching

[PA3DUV]

Jos,

Check out:

http://www.qsl.net/g4ftc/amplifiers/8170/8170_construction/8170_construction.htm

This gentleman (g4ftc) has some very interesting pages on construction and 
engineering considerations for tetrode amplifiers providing sufficient 
output and power gain.
The link above shows his very nice executed actuator operated band switch 
and choke switch.

Cheers, Dick
