A Beginner's Journey: The Philco 40-190

I just finished a complete re-cap of a 40-180 which included replacing a generic power transformer with an original (which was poorly wired in after what appears to be a catastrophic failure of the original), along with a new output transformer, and I can tell you it's pretty much a no-sweat, by-the-numbers operation.
One caution: normally the mica caps remain pretty stable and don't need replacement, but I've found the mica caps that control the pushbutton oscillators & trimmers are usually BAD and need to be replaced. Those are parts #23 & #24, and I've had great results from the 350 uuf replacements.
Good luck!
