That's a long formula. My eyes bled halfway through it. I was first introduced to the calculation by an Engineer when I was still plodding through my EE classes in college as a "did you know" moment. This site shows my explanation but explains it a bit better: https://www.rfcafe.com/refere...

Or if you wanna mess with math you can calculate the values using 10^(x/E) where E is the number of the tolerance family (i.e 24, 48 etc) and x is 0 to the max value of E. Then multiply the result by the decade of resistance (10,100,1k,etc). :geek: I had to use this in a program I wrote once to calc...

Did you perform the M101 alignment per that procedure earlier in the thread? Im pretty sure all my Vactrols are aged out of spec because the calibration resistance per the procedure was almost 30k and it still wasnt close. This is assuming I wasnt doing something wrong. I guess my first question is ...

Hello all, New to the forum and recently acquired a pair of Prisms, one a Texar and the other an early Gentner, both of the same design (same revision). I'm unsure if they are in spec anymore and have gone the safe route of replacing electrolytics, which helped slightly, especially with averaging. I...
