What kind of mic is it?
It's a subminiature tube, possibly a 5840, EF72, CV465 etc. Probably (but not necessarily) a pentode. It is written on the tube, but the photo isn't good enough to read it. They tend to be quite rugged and reliable.
Why do you want to change it? Is it faulty?
Changing it is a simple case of unsoldering it from the board and soldering in the new one. But be careful - it is very easy to overheat those circuit boards which causes the copper traces to lift, and then you are in real trouble.
If you are not used to soldering then take it to someone who is!

IDK - If it's new you should burn it in (leave it on) for a few days.
Hiss and crackle could be a sign of a bad ground are you sure that you have it put back together really tight?

If not, then drop me a message - we are in the UK and can probably sort it out for you. It could be dirt on the capsule either.

Hiss and crackle is either a bad XLR connection that is causing the phantom power to drop off, fixed by cleaning the xlr connections. Or condensation on the mic which you can fix by leaving it on over night or placing it in a warm dry environment for a day or two. I don't think the problem will be the valve.

So the problem doesn't really exist yet then!

It does in Europe - we go day/month/year.
(Personally, I always follow MSB* and write the year first - year/month/day. It's no good knowing it was a Thursday if you don't know what decade you're in!)
