Reply With QuoteEr, switch the amp off, wait for the valves to cool down, pull the old ones and push in the new ones? I can't think of any more that's involved apart from how you access them. When valves were the norm everybody could do this.

If you need to set the bias and match the powertubes, you need some more know how or a good tech.
The preamp tubes are easy, just pull them out and put a new one in - I only set the amp to standby. What's the amp?
THIS might help you as well.

No, you don't.Originally Posted by ibanezjunkie
Just do as MarkB said and you should be fine. Pay attention to how the pins line up as you remove the tubes, you want to line the pins on the new ones up the same, and don't force them or bend the pins.

I've swapped mine several times and have done some A/Bing between NOS tubes as well. The most time consuming part is taking off the BH's back panel. I also left off the tube covers with no ill effects.
Cheers
