So I picked up a TV-7D/U last week a hamfest and now have to determine which tester to keep. The TV-7 seems to work and may only need a calibration, and the 539A hasn't been tested, but comes with issues. I already have a Knight 600 which really does do a nice job for a simple emissions tester, and a Hickok 600A, but want to upgrade the Hickok 600A to one of the others and sell it and the other "big gun".
I want the "name" tester basically so I can sell off these buckets of tubes I have here with an authoritative test behind them and both the 539A and TV-7D have that. I like the smaller size of the TV-7, but it gives test results based on minimum acceptable reading, and the 539A I believe gives average of new, so one reads the lower limit, the other the higher. I have contacted Dan Nelson about the TV-7, and have his price schedule, so I know what that would cost.
What are your experiences out there with these testers and which would you prefer if you had the choice? I've already have two sets of inputs, but they are split, so it's time to poll here to see which one to repair, calibrate and keep.
Thanks in advance!!
