Late 50s philco curb find

[jr_tech]

If re-caping the entire set seems like a huge project, you might consider just doing the vertical circuit first (likely not more than 6-10 caps) then bring the set up on the variac and see where to go from there. You may develop some "troubleshooting" skills, by observing the operation of various circuits.

For grins, last night I powered up (on a variac) an early 50s 16 inch Philco that had not been turned on in over 20 years. I appears to have a vertical sweep problem similar to the one you describe. I intend to replace about 8 caps in the vertical section first (assuming that tube substitution does not fix the problem) and see where that takes me. Since I do not intend for this set to be a "daily driver", I will replace enough parts to produce a stable picture, and not "shotgun" the entire set.
