Pumping out the SV3 Mods must be tiring!! LOL! For now i just wired in a glass thermocouple from an old thermometer. it reads different to the SV3 thermometer by a LOT! So no real help but at least a guide to see if it is stable. I just wrapped a bit of wire and slipped it under some silicone ALA Sv3! Not pretty at all but at least i can see what is happening real time!
