Thanks for documenting your findings, Brett and Andrew - Very interesting.
I would like to stress that the warning Firepower has made regarding the discharging of the monitor cannot be taken for granted. CRT monitors can hold a charge and proper precautions need to be observed. If ever in doubt, please ask before trying to discharge a monitor.
I'll be following this thread with interest as I have a SWEP1 in line for a resto - so thanks again guys
