Gibson 440 need to replace power light

[cubanbass]

The power light is no longer working on my Gibson 440. I'm sure its an easy fix, but I have never needed to do this. What kind of bulb do I need and any other helpful advice will be appreciated.

Generally, when it comes to amps, if you have to ask, it's usually a good idea to take it to a competent amp technician. Should be a very cheap fix, and you'll know it's done right. Probably a good idea to have the amp checked out anyway.
