Not to hijack, but take pictuers with emphasis on how to take the chasis off for us noob's if you don't mind.
If you place your amp head on a table and slide it to the edge so that the feet are clear of the edge of the table you can look underneath the cab and see the chassis mounting bolts. More than likely they will have a chassis strap also. Once you know what you are looking for, remove your tubes taking care to not get them mixed up then remove the 2 screws at each end of the cabinet on the bottom. Do not remove the feet. Once you have the 4 screws removed you simply slide the chassis out. Be careful not to get your fingers inside of the amp. There are componenets in there that will still have a charge on them and can kill you dead. Once you have the chassis out, this is a good time to look inside to see what revision board you have if you are the owner of a 2 ch. The revision would be on the PCB below the blue C cell battery sized caps towards the edge of the PCB. It should say something like RF-1(x). The (x) will be the revision. This is also a great time to do a quick once over inspection for parts that may appear ready to quit. Caps with bulges should be addressed. Any signs of overheating or melting should also be noted. You can also look for your inspection dates from when it was being built if you are interested.
If you don't know what you are going to touch do not touch it. Do not touch anything inside your chassis unless you know what you are doing. If anything should fall inside, invert the chassis and move it around until whatever it was falls out. Do not sweat over the components and do not spill anything inside the chassis. I am not trying to scare you off but a little caution is better than death. Voltage will not warn you. It travels at the speed of light.
