have ( HAD) a ripple in my SW amplifone on the X axis. put the full amp HV and deflection kit from IanKellog in ( minus the mods i want to get it working first then move onto those) and still had the ripple. pulled apart the neck board and cleaned the pins, no change. onther known working board set showed same result. scope on the PS showed nice clean power on all leads and caps.
Fix ended up being a POT located on top of R24 & R25 ( on Ians cap map it's R76)
what a simple fix! now if i can figure out how to adjust the color gains in my red gun.
leaving for 3 weeks tomorrow for x-mas holidays and this would have bugged me the whole time! so glad i got it sorted!
 
messing with the gain and drive didnt do much, red was pink , monitor looked like it needed a degauss also but degaussing did nothing :( just for the heck of it i loosened the yoke and moved it back maybe 2mm and it looks showtime. colors are awesome and bright and sharp. the lower left corner can use some tweaking with strips but i think i will be just living with it rather than make it worse trying for perfection.
