Ever since I found out about these testers, I've wanted to get one. Well, I finally got my chance. It's the lower end 121 model rather than the 123, but still fun to use.

It came with all the original manuals, warranty, etc.

It works well too. These are supposed to be fairly idiot proof. Select the right card and insert it, pop in the tube and allow it to warm up, check the short lights then press "quality".

I seem to have cards for all the popular radio and TV tubes, but none for older tubes. That's a shame because it hase the sockets for old 4, 5, and 6 pin tubes. Anyone know where I can get cards or have them made ?

That's what always got me about how impractical these things were-when you need to update your Hickok 600? Get the latest revision of the roll chart. With this, you'll need to hunt to the ends of the earth to get ALL of those cards.

Still, I'd get one if I could-I still need to get a tester that does 4 pin.

Those are cool.

I'd love to have one of 600s, but they go for a fortune these days.

Looks like there are cards to be had. Too bad these arent for my model: http://cgi.ebay.com/Hickok-KS-15874-L2-Cardmatic-Tube-Tester-Card-Set-1000-/220601583437

Are any of these of help?

Maybe, I'll have to check if the 121 and 123 are compatible. Either way, thanks for the link - that's an interesting site.
