predicta i found today

[Tom Albrecht]

That's the 21 inch Holiday in mahogany -- the most common Predicta out there. I have one.

The original CRTs had very poor lifetime. If the original is in there, it's probably bad. If you're lucky, it was replaced at some point in the past. The replacement CRTs were much better and hold up very well. One thing to watch out for us that the original SF-21 CRT has a 2 volt filament. Don't blow it by applying the usual 6 volts!

You can find lots of threads here and on ARF about restoration of Predictas. Although some folks find them troublesome to work on, they're not that bad really. Good luck with it!
