Philco 16B restoration
#41

Not sure if this is the best place to insert this but here goes. I just redid a 16 series chassis and it turned out incredible. Plays amazingly well. Here are some of the things I ran into other then the usual recapping.

Speaker field coil open. Not easily repaired on this one. Most of the time I've found the solder joint between lead wires and magnet wire corrode and break. This one has a break deep inside coil. New speaker found, hopefully good.

Bypass bank is lettered a bit strange. I guess Philco chose to go in descending order of capacitance instead of alphabetically. My Riders did not mention that, but my Philco manual did. E B A
C D * Not used


I chose to restuff all my bakelite blocks. Found several resistors way out of range too. Changed all as I rebuilt it.


Tuning condenser mounts were gone. Dust lol. I used the replacement from Radio Daze Phil 90 but being a tad to short, added 3 SAE#10 flat washers to each to bring tuner to a good height and make it solid. I got washers from Home Depot, (Everbuilt 800331)

When I brought radio up with a test speaker, it worked quite well first try, but I always touch up alignment. Use an insulated or fiber screw driver to adjust IF transformers. Mine had a tad bit too long of metal blade, shorted B+ on First IF and radio began self oscillating, motor boating, and would work only if stage was de tuned. Turns out the .05ufd cap (ref # 34) opened up and once replaced problem was resolved and retuned stage for full output. I'm thinking the 1.2k resistor used to substitute shadow meter saved me a problem with that!
