Never work when you are tired!
Started working on the Latham again the other night. After changing all the bad color tubes I decided to check /dip horizontal current. It is over 200 mils! Put the alignment tool in the waveform coil instead of linearity and promptly messed up the synchroguide peaks! Then the scope went south! Sat down and looked at the schematic and said, STUPID!
Last night brought the other scope home and realigned the synchoguide, got a great picture but still too much horizontal current! At 110 volts I can dip to 196 mils! Strange thing is the screen grid on the HOT is way to high. Around 150 volts. With high current I would think it would be low!
Any ideas?
