The newer subs have a dc transformer (24v?), and incorporate some kind of rheostat/temperature feedback system. My older model is sensitive to voltage and ambient temperature fluctuations like yours is, I think all the older 120v ac units are like this as they have very simple electronics, just a dimmer into a heat sink.
Talking with Auberins on options to convert my old Sub into a Digital SUB!!!
Anyone know the MAX temp the head reaches?
For now i have asked to be able to control it to 700 Degrees Celsius, i know i will stay in the 300+ range only.
If this works and is reasonably priced, we could have a winner!
There is a digital temp sub, or you are working on a mod?
What did you have to do to mod it to get a digital temp readout?
Does anyone if there are any plans for an official digital temp sub?
