[Central-Electronics] MM-2 w/ RM-455

[AA6RK at aol.com]

Good Afternoon!
 
I have a few questions concerning adjustment of the MM-2.
 
1) Is there a component value change I could make to have the left/right  
front panel adjustment more at the midpoint of the pot sweep?
 
2) On receive through the IF, the wave forms appear to lean backwards from  
vertical. Is there an adjustment that could be made for that?
 
3) I have an RM-50 and would like to switch coils or the complete unit for  
an RM-455.
 
Thanks, Bob...
