Please take extreme care in replacing C114. The Lopt can be easily ruined through too much heat from the iron. I ruined a perfectly good Lopt once.

The frame output transformer is quite a weight on a PCB so dry joints are inevitable here. A stubborn case of intermittent frame collapse was once traced to a hairline fracture on the PCB close to the Frame output transformer tags.

It's looking good, well done.
