A Beginner's Journey: The Philco 40-190

After a day of ignoring the radio altogether ('Ramirez Helpful Hint #4--if it's not going well, set it down and walk away for a couple of days; you'll see the problem when you come back'), I started tracing the schematic. Part #44, 10Mohm resistor (which, as a result of the jolt, now measures at about 17Mohm) leads to a joint where a black wire comes to the joint between the 150 and 15 ohm resistors (60 &59); nearby is a bare wire off the rectifier that joins the blue and white trace from the speaker before going to the positive side of the 12mfd cap.

I crossed 'em, and I bet that's got a LOT to do with where all H**l broke loose. I'll also probably do some more tracing and verifying before I juice it up again, replacing all smoked resistors while I do so. (I figured this out between the schematic and the handy reference chassis. Interestingly enough, that 10Mohm resistor is nowhere to be found on my 40-190.)

Now to find if the Hammond 125E worked for another Philco Phan before ordering it as a replacement output transformer.

STILL NOT DISCOURAGED! Icon_biggrin
