Due to time constraints and a need to turn items around, item will be listed and sold AS Item recovered locally, tested and sold AS IS. This auction is for a Vintage SENCORE Align-O-Pak DC Bias Supply for Tube or Solid State Color/BW TV. This came from an old retired television station engineer. He had all kinds of neat old stuff like radios, antennas, test equipment, new and used parts, etc. I've never seen one of these before, but it wasn't too hard to figure out. There are three knobs and three switches for each channel - A, B and C. There are four wires that come out of the unit on the bottom right that are designated A, B, C and D. The red A wire is for the A channel, the blue B wire is for channel B, the red C wire is for channel C, and the wire designated D is the common wire. I plugged the unit in and took voltage measurements on all three channels. As seen in picture 7, the output voltage for channel A (green), with knob cranked to 25 and switch at +25, the output measures 25.3VDC. As seen in picture 8, I didn't get any output on channel B (blue). As seen in picture 9, with knob cranked to 25 and the switch at +25, the output voltage for channel C (red) was 26.8VDC. I went back to the channel B (blue) output and worked the switch back and forth a few times and got an output of 23.7VDC, which was a tad low, but not bad. I'm thinking that since this is really old, the switch might be a little dirty, which is the case with these older units sometimes. Might want to try and open it up and spray a little contact cleaner on the switches. This does work fairly well, with a little low output on one, but all the same does seem to work. This is an old unit that technicians probably used to put some voltages at certain places on the TV to test out the unit. This can also be used for someone that needs different test voltages when working on other electronics. I wouldn't trust the numbers on the dial, but rather would use a digital voltmeter and crank the voltage you needed, then use that as your output. Decent old item for the project person. Thanks for your time. Stored in location J2. Buyer pays shipping cost, please see shipping statement before making any payment, thanks!
