Anybody remember (or ever use) the old "Buzz-it" signal injector pen? It was uber-handy for stuff like this, generating a very jaggedy, sharp-edged waveform at something like 400 hz, rich in harmonics 'waay up thru the shortwave spectrum.

Yah, we had them..... They were good for stuff like this.... Never actually scop'ed
them to see what they were putting out.....

.

Yeah, I've heard of them, but we did not need them.

We had old fashioned hanging florescent lamp fixtures over our work benches and the frames were not grounded. (The fixtures were industrial surplus and had been made during WWII.) These lamps radiated RF so badly that a plastic handle screwdriver touching the set would inject that signal.

As far as scoping them, that happened all the time, so we had to turn off the overhead lamps to use a scope on the set.

Try a modern(electronic ballast) florescent fixture if you need a broadband rf splatterer. :D Even the LED light bulbs I've tried sound like a buzz saw coming across my wireless fm intercom system. :sigh:

Electronic ballasts.... what a sad joke! I put a couple in the shop and it drives most of the TVs and AM radios wild! Ended up replacing them with magnetics!

Somewhere in my boxes of stuff I have a "Mosquito" signal injector pen that someone gave me:

I know the one I used was not like that... Ours I think the switch was on the end like
a regular pen... The front did not have interchangeable tips that I knew of.... You pushed
the back end in and over a little and it stuck, then touch something and the noise was
everywhere.... I remember it was not my first choice tool....... It was the same size,
same looking tool.... I bet a buncha people made items like that....

.

Phil's link shows a pair of items, the "Stethotracer" with the interchangable tips and earpiece. It's for tracing only.
Then the companion 'Mosquito' which is an injector only. It's just about identical to the 'Buzz-it', with the same 'click & stick' pushbuton on the end, just like a penlight.

Yah, ours was just for injecting something, I have not thought about that thing in years......

Sorry it's been so long guys. I work 50 hours a week plus 3 hours a day drive time doing component level repair on electronics for the railroads. It's almost impossible to work on my antiques during the week with only 3 hours before bedtime when I get home. I will be getting back to the Teletone this afternoon and will try all of your suggestions then. Thanks for all of the help.

If I recall correctly, it was a "Don Bosco Mosquito." I had one way back then. It was very handy for radio or audio repairs. Not so much for TV though....

got a picture!
 

Well guys after far too long I finally got back to my old teletone. After recapping the tunerand some minor adjustments I finally have a good picture. With the sound being only about half volume but otherwise clear I think all I have left to do is an alignment.

Sorry about the photos being upside down. I guess that's what i get for drinking beer while working!
