Philco 39-30 restoration
#23

Your 39-30 is coming along very nicely, Bob Icon_thumbup

I don't understand why your pushbuttons would not tune below 800 kc until you changed (11) to 600 pF? Very strange indeed! These caps are always bad and I always replace them just like I would a paper cap, but I generally keep 390 pF micas in stock for this, since 370 isn't a standard value. I haven't had a problem yet like you had, knocking on wood...

One would expect the inductance of the coils in the pushbutton assembly to change a little over the decades, but to change that much is unheard of. Are the pushbutton contacts good and clean? As thorough as you are, I am sure that they are very clean, though.

Sorry...I am at a loss to understand why this happened to your particular set...I hope something doesn't go "pop" later on and you find the lower pushbuttons tuning LW! Icon_eek
