Yesssss yes.... thermistor is where I started with all this... http://www.learnmorsecode.com/laminator/index.html http://www.learnmorsecode.com/laminator/pic/index.html we landed on the diode discussion because the PACE PP330 circuit can be hacked by for higher toner melt temps by changing out two resisters http://www.learnmorsecode.com/laminator/gbc/pp330.jpg On 01/01/2017 08:35 PM, Mark Lerman mlerman@...
