Cardmatic tube tester

As [Usagi] has been working on some tube-based projects, he decided he needed a tester so he built one. You can see the results in the video, below.

He does have a traditional tube tester, but it uses s of volts which is a different operating regime. We think of punched cards as old-fashioned, but still squarely part of the computer age.

Turns out, cards were in use way before they got conscripted by computers. Jacquard looms are one famous example. The U. But in the s, you might have had a punched card machine on your electronics workbench. The Hickok Cardmatic was a tube tester with a difference. While you, as a Hackaday reader, might tear into a busted TV at your house and try to fix it, most people today will either scrap a bad set or pay someone to fix it. TVs are cheap and rarely break, anyway.

Most of the parts were reliable, but the tubes would wear out. If you were lucky, there was a diagram glued inside the cover that showed where they all went back. Then you took them to the drugstore.

It can be difficult for modern eyes to make much sense of electronics from the s or earlier. The good news was that the machine had nearly all of its original parts, down to the Hickok branded tubes in the power supply. Unfortunately it looks like a few heavy handed repairs were attempted over the years, with a nest of new wires and components intermixed with what [Cat0Charmer] actually wanted to keep.

After undoing ham-fisted repairs, replacing the dud components, and installing some new old stock tubes, the tester sprung to life with renewed vigor. With a DIY calibration cell built from the schematics in an old Navy manual, [Cat0Charmer] got the tester dialed in and ready for the next phase of its long and storied career.

Today was the music city vintage radio club swap meet in Nashville. As nice as that is, there are a whole lot of tubes that i don't have cards for.

Hickok Cardmatic Tube Testers

Does anyone have that chart or database? Electronic M. One can replace the card reader interface with a computer and run every setting it was ever made for and much more There is a company that does these conversions. What I want. Way too much money. I probably have a need for around tube characteristics, just different from most of the ones that came with the tube tester. Hey all, the ebay seller who says they have a info manual on test conditions for tube testing.

I was expecting a manual, that gave a x-y coordinates for the punch cards. The manual only states the test conditions "filament voltage, screen voltage etc etc. Doesn't even list the pin out of the tube. Reason: Making it more concise. Does the manual not list a procedure for punching your own cards for new tube types? I have a Western Electric version of the Hickokand it explains exactly what each hole location controls, and how to translate desired test conditions and tube pinout into which holes to punch out.

The tester also came with a supply of blank cards and a special hole punch for this purpose. An involved process, that takes a good bit of figuring out, but it works. May give you some ideas.

Also you need to dl the stupid djview program to open the file, there's a dl for that in the fine print. Other than that, my recommendation would be to use existing cards to determine which holes do what. Google for Hickok test data or tube test sheet, and you can use that data to cross-reference what you have on the cards for a given tube, and then determine what hole does what.

Knowing that, you can then make your own cards. And maybe test some known-good tubes first to make sure your new cards work right. Last edited by MadMan; at PM. Originally Posted by MadMan.
