[Amps] AL-1200, Band Switch

[Andy Diethard Hansen]

Hi All,

Symptom:
The band switch (mainly) in the 15/17 m  position shows again bad contact.
150mA grid drive create 500W or 1000W (ok) out on 17m, depending on
direction of switching/rotation (up to down and vice versa).
Happend already before and got fixed 1 year ago by dealer replacing the
switch. Now I want to do it better by myself.

Questions:
Could this be parasitics? Have not checked with spectrum analyzer or scope
yet. Any comments/help/fixes/experience? Tnx
