Buying from multiple reputable sources and at different times is a good idea.

My experience has been most readings fall within a 1.5v-2.0v window within every batch I have purchased.

The range itself has varied between sources and timing.

The last batch of 100 I purchased from Mouser read between 6.0v and 7.5v with a 15k resistor, none were withing range for a proper Plexi build.  

But this last batch of 100 I purchased from Newark, most read between 3.7v and 5.5v with a 15k drain resistor. 10 of those were between 4.6v and 5.1v with a 9.25v source, and should work well in the Plexi. A few more were just outside the optimal range, but may still work well.

Crazy Brian has taken the time to sort these J201s and find good use for multiple pedals. Maybe at one point early on he figured what am I going to do with all these that are outside the targeted range, and then developed the Plexi, '57, '65. Sovereign and Pinnacle to make use of the wide tolerances...

Wonder if he has the "power" to request J201s within his specifications?
