[HAM] Vibrato and Non-Vibrato

[David Anderson]

Jordan,

To elaborate on Scott's approach, I've read that the way to check the  
relative volumes of the two preamp channels is to note that Chorus  
will always be a bit louder than Vibrato because the Chorus settings  
put an extra resistor between the line box ground and the actual  
organ ground. The goal that I read about was that  Chorus (C- 
settings) should be slightly louder than Normal/non-Vibrato and that  
Vibrato (V-settings) should be slightly lower than the Normal/Dry  
signal.

When I've rebuilt preamps, I've found that it's not too hard to throw  
the balance off so that it has had to be readjusted.
