Get yourself a good power supply, chances are you going to need to upgrade to a new one if you are getting a bigger tube. I got a cloud ray 150 watt power supply with the digital read out and external LCD screen I also have an analog MA reader but the digital is spot on, this way you can fine tune your laser and not worry about overdriving the tube.
Last and not least, get yourself some high voltage connectors. These will insure a secured connection I have seen so many times people don’t properly secure the connection and you will have high voltage electricity arching which can be lethal.
Overall I am very happy with this tube and highly recommend it.
