It's no surprise that the original caps, which have a fairly high
negative temperature characteristic, change value as they warm up --
they are SPECIFIED to do that. :) I'm wondering if it was a pricing
decision by Ten Tec to use them, or if the designer was attempting
to compensate for heat-related drift in the other direction by the
inductor?
