Well it didn't last long, I have the red and yellow lights of death, but never fear after investigation I've found another design fault, and possibly why it's failed and why the base gets so hot! The heater is remove able (not soldered to the board) the leg of the internal 10a fuse is a push fit and so is the yellow lead next to it. I can see where the joint has oxidised and become a resistive joint, I'm assuming it's this that has caused the internal 10a thermal fuse to blow causing the flashing lights.
I still have the correct resistance across the heater post fuse so I maybe tackling a fix ( if temporary I need my meds)

I'll update if I fix it. If it was easy to put pics on I'd do that too.
Fixed! Removed the fuse (temporarily) soldered the heater to the board switched on working just got to rebuild it for a vape! Was starting to get worried I'd have to get the extreme q out!
I'd say what I've found is a serious issue!! Heat up time from cold is now super fast!!!! The temp jumps is 3-4 degree at a time right the way up I didn't time it but it was about 1.30 at a guess.
Edit: Just timed it from 24c to 190c comes in at a super speed of 1 minute 18 seconds
Happily back vaping!!!
I suppose being a geek with electronics has helped me a bit but I hope I can help others!!!!
