Ron,
Oh so you know my secret I really don't know how to find stuff in the library. [Image: https://philcoradio.com/phorum/images/sm...on_lol.gif]
Tnx for popping in filling the gaps on the "other" 200/201. So now it's one of two that have appeared out of the woodwork. I thought that there was 3 or 4 of them as pictures would show up every so often when the same one changed hands and my brain would mark it down as one more.
Bob,
Unfortunately an inductance/capacitance meter is something I haven't picked up yet. [Image: https://philcoradio.com/phorum/images/sm...on_sad.gif] Most of the test gear I use is from the '50s with the help of some modern way of checking it's accuracy.
Perhaps nowdays the only way the get a 10KC+ signal would be from a LPAM. Over here near Philly there's not much on in terms on music. A lot of talk, sport, news, and the like music not so much on AM. SW offers a few music stations in the evening like WTWW @ 5.085 KC.
I'm not much of a polishing kind of a guy.
Mostly servicing and cleaning as needed. If the IFT grid lead's insulation is failing I'll pull the cans off replace the wiring. Clean the dirt/dust from the trimmers and use a soft Scotch Brite pad the remove the corrosion from the cans. I want it to look pretty original if possible. Will replace the known foul players e cap and foil/paper caps. Check audio transformers, resistors, chokes/field coil, and sm coil. Even though the 70H 10ma didn't look so good nor smell so good it was ok. You are lucky those 6-32 screw in the tops of the IFT can be a little devil to get out without breaking the screw or the ceramic.
Looking good so far!

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
