[Test-Equipment] Another boat anchor - Del Electric High voltage supply?

[Carl]

Old TV's used a SS tripler module, also many computer monitors but the TV's 
are likely a much higher voltage.

Ron - Take a look at a Heath HP-23 series power supply schematic.

The high voltage for the plates was derived by either doubling or
tripling with diodes!

Just be SURE to use the appropriate voltage rated diodes!
