Philco 16B Code 125 Electronic Restore Project
#29

It’s Alive!

I sat down after lunch today and dug in deep. I got to the point of first power up and it works on all bands! I sent Paul a video so he could see it first hand.

I have to fix an intermittent volume control ground connection. I had the control open to clean it, and I could not find anything amiss. I think it’s where the control meets the chassis. It’s kind of a poor way to ground it. I may just solder a wire to the unused terminal and be done.

I also saw the shadow meter working briefly before it developed a short on the B+ feed side. I saw the error of my ways which was how I routed the leads out of the coil form. I have a plan to resolve this.

I did a quick tweak of the IF cans which were way off. Afterwards, I heard a broadcast band signal with the generator set between .5 and 1 uv applied to the antenna connections. Impressive!

Important note:

There is B+ on the IF trimmer tuning screws! I checked before I adjusted anything. The directions said use the Philco fiber tool, and that’s why. I remembered working on a Midwest radio years ago, and that was the case there too.

More to follow. Don’t change that channel!
