Update on the Philco TV-123.
After 6 months of on and off restoration I have the TV-123 operating. Luckily there were no major problems to fix, replaced all the "black beauties" that Philco seemed to love, lots of electrolytics, HV capacitors that were shorted, and a few bad tubes. The biggest problem I ran into was having to reconstruct the reactance tube coil. The original uses a hex style slug for adjusting, but after 50 years the coil form shrunk and as soon as I moved the slug it froze in the form. Of course trying to free it only destroyed the slug and form, a spare one from another chassis did the same, so I rewound the coil on a new form that uses the brass screw style adjusting slug.
Now on to the second one.
