Original poster: Mark Fergerson <mfergerson1@xxxxxxx>I recently acquired a type 10B Powerstat for US$1.00 which is a steal, but when I got it home I noticed that the wiper button is missing. Can I just whittle a new one from say a D-cell center carbon, or would that be too resistive? Any better suggestions before I go ahead and burn the house down?
