I'm having some amp problems. I've had my valveking 112 for about a year now, and for the past month or so the amp will make a loud hissing noise. The hissing happens about once every ten minutes and will last 5-30 seconds. At times it almost sounds like wind blowing. Is the a sign that the tubes need to be replaced?

Sounds like a failing tube. I had the same issue even when my amp was new. It was a faulty tube.

Yep, my VK did that when I had a preamp tube going bad.
I replaced them with(and love):

V1: Tung-Sol 12ax7
V2: JJ ecc83s
V3: Sovtek 12ax7LPS.

Power Tubes: JJ 6L6-GC (very nice growl to them)

The resonant frequency of the clitoris is too low for the guitar players to take care of.

All I would need right now is pre-amp tubes right? What are the benefits of replacing the power tubes?

New tubes is like buying a new amp. You'll go "Oh yeah, that's how it's supposed to sound!"

It is more likely to be a faulty power tube, preamp tubes last for donkey's ages.

You could always bring it to your local guitar shop and they'll test whether it's a power tube or preamp. In my case it was the preamp tube that went first but that doesn't mean it's the case for you.
