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

[Carl]

For AM you want to test to at least 4X the plate voltage; this makes 
10-16KV+  rather a standard part of the test.

Several megohms as a current limiter protects from tube damage as the 
voltage is slowy increased while watching leakage current.
