I bought 3 thermostats from Smokin Tex. Used one in a Smokin Tex and 2 in a couple of SM008s that I repaired. You have to call Smokin Tex directly to order. Same thermostat is used in all their analog models.
One of the SM008 had a stainless steel shield that covered the bulb. Found out it deflects so much heat that the Smokin Tex thermostat doesn't work well unless the bulb is exposed. So I used a couple of stainless steel clips to hold it in place instead of the OEM cover.
