Will do! Is there anything I need to be wary of while taking the chassis out of the cabinet?
Unplug the two reverb cables on the underside of the chassis (note their location for when you put the chassis back in)
Also unplug the cooling fan. It too is plugged in underneath but on the left side by the Power Transformer.
A bit of a pain to "reach" it as it's a tight space between the PT and the side of the cab but you'll get it unplugged.
Before doing the above and taking out the four mounting screws:
Turn the amp on have the power switch and standby in the on position. Make sure a speaker cab is plugged in too.
Plug in your guitar and play a chord. While the chord is ringing turn the amp off using the power switch (not the standby switch!)
You'll hear the chord fade out and maybe a static-like crackling sound as the volume fades to nothing.
This will help discharge the caps before you pull the chassis.
But to be safe don't go poking around inside the guts after you get the chassis pulled.
As for more help ID'ing the amp read this thread:
