Title: EICO 667 tube checker & 0A2s Post by: wx3k on November 15, 2008, 07:15:14 PM I tried to test a 0A2 this evening. Oddly, with all the correct settings on the checker, the Merit test does not produce an upward deflection of the meter. The tube glows at the bottom of the tube. I put the tube back into the receiver I was working on and checked the regulated output...149 volts. So what is the issue with the 667 ? It appears to work on ALL other tubes I checked on it.
