Noticed smoke and smell from my 60W shenui and saw the tube power supply was the culprit , blackened casing etc. Laser was on but not firing at the time..
Anyway , removing the tube PS and plugging the laser back in without one tripped the circuits..odd...........
On the same circuit is the chiller and the cheapo extractor.....
So we unplugged each item to see what was at fault and it turns out the extractor is faulty...plufg it in , it trips the board..
Now , apart from the fact that the laser /chiller/extractor is on the same powerstrip , there really is no connection between them... they all run independantly
PS ( has no fuse ) was really burnt up inside...So i wonder if the extractor took out the PS or vice versa...nothing else was affected.
Had a spare PS and swapped it out and 5 mins later , all is running A ok..(barring the extractor)
