I think I may need an intervention.... Of the 17 shown in the photo I have 8 of them and another 4 or 5 not shown or part of other combo equipment.

Of all those I only have a 324 as a casual backup generator. And only then because the seller wanted 15$ but took 5. And it was not in bad shape at all. I cannot recall if I had to do anything besides recap and align it.

I'm spoiled on my HP 606B. Huge and heavy, but puts them all to shame.

I think Rich KB8TAD is on ARF. Maybe he will stop by and tell us if his fine collection has expanded.

I have just the TV-50 and the Paco. Guess I'm not addicted, at least to SGs.

Thanks for the reference Peter. I continue to write for the follow-on e-magazine to Monitoring Times, - The Spectrum Monitor.

If one is just collecting to be collecting, that might be considered an addiction but working and having fun with these is the object of the game and the article. The fun is in studying and understanding the circuitry and knowledgeable use of these pieces. I have passed some of them down, same as with tube testers. Not shown is my daily-driver sig gen, a little Viz WR-50C and some specialty devices such as a military version of the HP-606 and Gen Rad pieces.

The article was intended for folks with less experience than the average here. The pictures in the article show clearly what happens when these simple service generators hit a tuned circuit, going from variously-shaped pulsed scope displays (as often complained about on this forum) to beautiful sine waves, something that happens inside the radios we service. And it shows some of the simple tricks in using these for servicing.

Cheers & 73
-- Rich

You're welcome Rich... I thought it was an "ideal" fit here... and a hit. It seems to be... no?

All I have is a Hickok 288X military version that required only modest restoration. If you ever saw the waveform of it on a scope, you'd wonder how it made the grade of being government equipment. Still, Hickok was no slouch when it comes to good equipment. Since I've successfully done a few alignments on shortwave receivers and it did the job, I have no complaints. I bet back in its day as a service generator in an ordinary radio/TV repair shop, the customers were happy. Plus, it's beautiful.

Me too. I think Rich had to redo his web-site with new URLs. Try this one, it works for me:

Such a pretty Philco. I've got that one here, and it's a real showpiece. I've also got a few of the silver swirl finish panel Philco test pieces, also quite attractive stuff!!
