Hi everyone, Got a problem with one of are frick boosters unloading I am suspecting a bad glide seal. So here's what i got. On quantum panels in calibration screen if i try and unload the slide stop it takes forever like 15 minutes to move from 5.0 to 2.2 if i move the slide valve at all this loads up the slide stop even if i have it have the slide stop on unload. Replaced the slide stop potentiometer and replaced the Yuken valve just to rule these out. I valved off the slide stop Yuken valve still moves the slide stop when i move the slide valve? Any other recommendations?
