Restoring a Predicta Tandem
#11

The Tandem uses a 9L38 chassis.

What type of caps are you ordering ? Use plastic film caps rated in DC to replace the paper and "bumblebee" caps. I just get 630 volt caps for all EXCEPT for the 0.0015 uF cap in the vertical circuit. It MUST be rated for at least 1,000 volts!

You will get about the same voltage on either side of the thermistor. Especially if the tubes aren't lighting up. What resistance do you measure across it ?

Ametherm SL15 22101 it's 220 ohms cold and rated for 1 amp. That's the highest resistance rating I've found. you can put two in series to get 440 ohms cold. It's well suited for the 0.6A string in this set.

I think that tester will only tell you if the filament is burned out or not.

These are not easy TVs to restore, but are also very collectable and well worth the effort.

Here is a link to a YouTube video series I did about restoring one of these sets: https://youtu.be/01RP3SPzpNE
