Hi Bruce,
 
sounds like I can probably do the 200MHz multiplier board adjustment. I  
wonder how much improvement that by itself, with the hardware mods will give?  I'm 
just afraid to make things worse.
 
I used to work with TV's, and it took me years to learn how to adjust a  
good-old picture tube correctly. It's more an art than science. By giving the  
service manual a quick glance, I fear this is similar.
 
bye,
Said
