Hi all. I had a problem : when I placed the RI/XIT pot in center position, I had on offset. Yesterday, to add a RIT and a zero-beat led in the front panel, I have unmount the front panel and checked the pots. When I have built the front panel, I have put the logarithmic pot for the RIT/XIT instead of audio... After swapping the two pots, the problem were naturaly solved. 73 -- F8DQL - UFT 1116 K2/100 #3249
