Another 16B, more fun - BrendaAnnD - 03-18-2013

Just got in another 16B (I liked the other one so well I thought I'd pick up another just because I could.

This one's in much rougher shape than the other in many ways, not as good a cabinet, tuner is virtually hanging loose on top of the chassis, volume control shaft is broken off, tuning mech is bent and of course the rubber idlers are all toast.

After a preliminary check for low resistance paths and finding none (only completely open electrolytics!), I subbed in a temporary filter cap and brought it up slowly on my variac. No noise, but no hum, either.

After this, I cleaned the bandswitch and hooked up an antenna (after removing the dial assembly, so I could actually move the tuner), brought it up again, and still no noise. HOWEVER, tuning up the dial, there was the familiar AFN signal and down a bit from there was my in house AM signal.

On to a quick IF alignment (someone had "tightened all the screws" and voila! actual noise, and the extra reception that goes along with it.

And guess what else? ALL 5 BANDS WORK!!! All the way across the dial! Even the shadow meter works.

Of course, now I need to start the complete recap and change the out of tolerance resistors. But that's the fun, isn't it?

Cool! It is fun to bring one back to life! What are you using for your in-house AM transmitter?

I'm currently using an old AM-88, can't remember the manufacturer at the moment. They were made in California.
