Replacing a Flashtube

[joey]

Ok... the flashtube on my Speedotron MW3R head isn't firing, and I

need to know what is wrong with it. The modeling lamp works fine,

but the flash does not. The cylinder-shaped cover surrounding the

flash bulb is loose, and I don't know how to make it stay put. Does

anybody know what the problem is, and how I can fix it? If the tube

needs to be replaced, how do I remove the old tube, and install the

new one? I can't seem to find an answer anywhere, not even in the

Speedotron manual. Thanks!

Nevermind--I figured it out. It just pops out, instead of screwing in (no wonder the Speedo instructions are so vague!). Luckily everything works fine now.
