Philco 90 crackling
#9

So seven wires to the tuner and 2 wires to the dial lamps disconnected and I had the tuner unbolted and in my hand. Then I removed the dial scale and tuning knob/drive, and then disassembled the trimmers, carefully counting the number of turns it took to back the nuts off of each. I removed the sheet of mica from each, reattached the copper adjusters and it was time to put it in the cooker, er I mean ultrasonic cleaner. It JUST fit in my Harbor Freight model, and just that I could get the water level over the meshed tuner. So I ran it through four 480 cycles with heat and a bit of simple green, two with the bottom down, and two with the bottom up. I took it out, rinsed it off to get the soap residue out, then took the air compressor and blew it down good to dry it off. Added a few drops of oil to get it moving nice and smooth. Then it was time to reassemble the trimmers, reattach the dial mechanism and scale, install new grommets and resolder the new wires on. Fingers crossed I tried it out and remarkably I received a station! After an alignment it's back to performing like it should with only an occasional pop, nothing like it was. So apparently the heart surgery was a success and the patient survived. Lesson learned I should have just bit the bullet and did this when I did the recapping. Yes it was a lot of work (took the entire afternoon) but judging by how black the water in the ultrasonic cleaner was from 91 years' worth of crud, it needed to be done. Here's how it looks now, all squeaky clean.
