Like he has lased:
CALL REO and get the real specs for the PSU, its easy to install a wrong one, which will be short lived. Also if it is killing PSUs, replace the ballast resistor with a wirewound or metal film resistor of the correct value and wattage.after a long tedious journey of rotating and cleaning the prism, I finally got it to lase at full power. the main issue was a thin layer of dirt on the brewster and prism which I could wipe off and with every pass, I saw an increase in power. It was incredible! I got about 3.65mW of 632.8 and unknown powers of 612nm, 604nm, 594nm.

Then, while I was enjoying the pretty photons (which look terrible on camera) , the universe decided I had enough fun. The power supply started screaming and then conked out.. So, I had to remove the tube from the casing and I'm now looking into finding a new supply. I'm hoping I don't have to go through too much effort realigning and cleaning but, I probably will. At least I have a feel for it now so, it should be much easier. Thanks to everyone who gave me advice. It really helped out in fixing this thing up.
I read that the tube needs 2.2kV and the recommended current is 5.25mA but I just sent REO an email to verify.CALL REO and get the real specs for the PSU, its easy to install a wrong one, which will be short lived.
