Right! I'll make the correction. Thanks.

Pardon the question of a rookie, but what did you use to clean the chassis? You do fantastic, detailed work. I wish my dexterity and eyesight were good enough to do work like you do. Quite impressive, and thank you for sharing your work with those of us trying to learn.

Amazing work!

I cleaned the chassis by taking it to the "Quarter" car wash. After taping placards and such I clean it by using the "Presoak" setting. This gives a gentle wash. Then I use the "Spot Free" setting to rinse it off.

Then either it goes outside in the hot Texas sun, or it gets baked in the oven at the lowest setting for an hour. Then the controls are sprayed with cleaner and WD-40.

Now its clean enough to work on.

Thanks for the kind words.

In 1965 I was working for Georgia Power Company and we bought a Tektronix storage oscilloscope - a big purchase back then. Included in the purchase price was a one day class by Tektronix. The Tektronix guy started off telling us how to periodically clean the interior of the scope. He recommended soap and water, just like your method of cleaning, Crist. If Tektronix recommends it on a $3000 scope, it should be OK for a Philco Predicta!

Exactly!
