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
