*** Western Electric Computerized Cardmatic (Bitmatic) KS-15874-L1 *** Did I say computerized? You bet! This Cardmatic doesn't need any cards! Here we have a refurbished Hickok-made Western Electric Cardmatic tube tester for your consideration. That alone will turn some heads, but this one has been computerized! The computer interface box is new, right off the production line. And now an IBM ThinkPad Laptop is included! When I say it has been refurbished, I mean it (all of this work was performed by me personally): * All electrolytic capacitors in the power supplies replaced with long-life 105 degree parts * Grid Signal Amplitude potentiometer sensitivity mod has been installed * 5U4 rectifier tube has been replaced with a solid state rectifier to remove the heavy filament load from the power transformer * All push button switch decks have been disassembled, cleaned, and reassembled * Selenium rectifiers replaced with silicon diodes * Full Calibration * NEW Calibration Cell Included! If you don't know about the Computerized Cardmatic Testers, hold on to your hat. There is no way to list all the features in this auction, so see this page for my web page that explores this tester fully. The software is supplied on a bootable thumb drive that boots directly into the software. Plus, an IBM ThinkPad laptop computer is included! The ThinkPad is great because on it the software boots instantly and it is 100% compatible with this system. It is very easy to use, and it is by far the fastest way to test tubes on the planet. There are no switches to set, even when testing Compactrons and Nuvistors. You don't even have to set the line adjust for each tube, the software does it for you! Here are just a few of the features: No cards needed -- even the calibration cards and the instruction cards are programmed into the database. The database contains the equivalent of 3,924 Cardmatic cards. Built-in universal adapter provides 3 additional tube sockets including 9-Pin Novar, 12-Pin Compactron and Nuvistor! Plate current jacks for an external current meter are provided on the control box. Fully tests for heater cathode leakage, shorts, gas, transconductance, plate current, cathode activity, grid current, grid emission, voltage drop. A chart is displayed on the screen during each test which converts the meter reading directly to micromhos, milliamps, or volts. Programmable test parameters -- you can program and store your own custom tests. The ultimate in versatility. Built in calibration routines for the highest accuracy possible. Instructions are printed right on the screen. Uses sealed computer controlled relays, meaning no wrong settings, no dirty switch contacts, no faulty readings. For tubes that have more than one test the heater remains powered between tests. No extra warm-up time. Heater voltage can be varied while testing. Handy for rejuvenating tubes. Not normally possible with Cardmatics. See other advanced features. Turns your tester into an exquisitely sensitive curve tracer. Print curve charts with just one keystroke. Even more tube sockets are available as an extra cost option. These include Acorn, 10-pin Miniature, Decal (which is a different type of 10-pin miniature), and 7-pin Nuvistor . Contact me for details. Do you already have a Cardmatic and want to get it Refurbished and/or Computerized? Check out my other auctions! This tester comes with a full money back guarantee. The card reader has not been refurbished and is not guaranteed, but it is not needed for computer operation. The suitcase type handle is long gone. This tester is very clean overall, but the cover that came with this unit does not latch down. It can be still be used as a dust cover when the tester is not in use, however. This system comes with a full money back guarantee and a one year warranty. Shipping to outside the continental United States will be quite expensive ($500 to $600 for Europe). Contact me for a shipping estimate if outside the US. You don't get glitz or pizazz on my eBay pages, just really good products and unbeatable service. I specialize in calibration (see my calibration test bench), and I build Computerized Tube Testers, so I stand by my test results. :)
