Philco "Woodstock" 19" BW

[DavGoodlin]

This 1964 VHF-only set came from a fellow collector with some of the paper caps already replaced at the key spots, vertical section mostly.

After testing the Lo G2 CRT with my one tester, without a G2 setting, I was sure it was bad. Not so with a B&K tester set properly to Lo G2.

I finished the paper caps last night and was very impressed with the picture. But vertical is stretched in the middle and I haven't tried a 17JZ8 yet, sure I have a dozen of em.

The cabinet design looks like an early 60s Early American console style was compressed into a tabletop set for a very tiny apartment

This set has all the plugs for an easily added UHF tuner, including antenna screws on the back cover.

The HV anode cap was cracked open, so I found a nice replacement and slipped it on.

This set does not use a voltage doubler, so B+ is 145 volts and the 4-section cap tested OK, so it stays.
There is an extra switch ganged with the power switch that disconnects the brightness control, so no bright dot when you turn it off. On the schematic from Electronic Technician Magazine, the clusterf-k vertical intergrator N3 is detailed.
No wonder restoring a Predicta is so component-intense, Philco went nutz with these.

Getting under some of these caps wasn't easy either. Just for good measure, Ill hit all the solder joints on the big tube sockets, they look iffy.
A bright light does wonders helping you see the traces from the top of the PCB, allowing yout to put the soldering pencil on the right spot.
