Philco 46-480 Replacing Field Coil w/ Perm Mag (I know I know)
#32

Hi Rev,

LOL on the perm. Your lightning rod comment reminds me of a character in the John Candy movie "The Great Outdoors" When asked how many times he was struck by lightning, the character who had a white streak in his hair replied "Sisisisisixisixisixty six times in nnininin ththththte hhhhehhead!!

Maybe that is why my hair is curlier than my 3 brothers and 2 sisters! "Old Restorer" posts the number of times that he has been electrocuted.

The fact that I made it into adulthood without being blinded, maimed or killed, other than being a little mentally ill (so my Wife tells me) is proof of a loving and benevolent God (and boy, do I owe Him!)

If i got too jargony, sorry. let me know and I can elaborate, but some of my acronyms and abbreviations:
AA5- All American Five, the description for the very common 5 tube circuit consisting of a Pentagrid Mixer, IF stage, Detector and 1st Audio Tube, Audio Output (power amp) tube and Rectifier. Most folks define an AA5 as an AC-DC set as opposed to one with a power transformer.
Xformer = Transformer (X = trans)
OPT = Output Transformer
Cap= Capacitor (condenser)
OSC= Oscillator (your radio has a separate Oscillator and Mixer as opposed to the "Pentagrid" mixer common in "AA5" radios
IF = Intermediate Frequency
SMD= Silver Mica Disease Many IF transformer assemblies from newer (about 1948 or later) radios had built in capacitors of about 100pF (picoFarad). Apparently, the mica would crack, the silver would corrode and the cap would short. This also happens to mica caps with molded plastic cases.

Do try the simple things. Wiggle the oscillator mixer tube, the 2 IF tubes and the detector tube in their sockets. If a lot of static while wiggling, clean contacts. also slowly turn the band switch to see if you get static or if the radio starts playing. Then go for the heavy stuff that I wrote about.

Good luck and keep us all posted!
