I have just replaced the HOT and Flyback on a G07 that was killed by a power surge.. Havent done done a cap kit yet..This is a repair for a friend, and I dont have the origional tube/yoke.. My test tube appears to have a resistance in the ballpark.. (50 V, 2.5ish H). When I fire it up, I get a tiny image, maybe 3/4"H by 8"V.. Would this likely be the yoke mismatch, or is there something else fried on the board?. B+ was around 125v.
Now the 4600 has a problem on the XY board. Im getting no horizontal oscillator, therefore, no HOT squeal, no HV. The Horizontal drive transistor looks ok on the meter. Has anyone seen any common causes to look for?
