CTC-7 metal table top

[DaveWM]

I picked up a new 1 meg from rat shack, but before I installed it I tried cleaning the old one, that made a HUGE improvement (I must have missed that one in the 1st pass). I used the opportunity to demo the pot function both before and after the cleaning to my teen daughter, She enjoys watching dad work on stuff and we use it as a learning lab (both using digital and analog meters) on what a variable resistor is (in this case its configured that way) and the advantages of a analog device in some settings. working on the color code with her as well.

I think tv's make great labs, for troubleshooting, and general maintenance (like cleaning pots and switches etc....) of vintage electronics. I know its dead end tech but I still think there is an opportunity to learn some of the basics.

hope to get to the xtal later and the tube checks on all the rest (not much to be gained there as a working set is a better test, and other than the soft focus and the color lock being intermittent, its a working set.
