update: it's gotten quite a bit more powerful
actually, would it be possible for you to take your OC out and look at the part number? im curious if you have a broadband one. mines a lame 632.8 one but ive heard the standard is 612-640nm. the tuning prism however is coated for everything possible so it doesn't care. thats why i can tune to orange with an external OC.The bell\reservoir cracked when attaching a new seal-off stem. The bore is intact so I may try again but for now.... :-(
Are those alternating connected bands that run down the length of the tube for starting the discharge? I've never seen a tube big enough to need something like that.
