Based on your description my expectation is that you had a voltage
breakdown of the bleeder resistor. While we normally think of resistors
in terms of the power they can dissipate, there is a voltage limit that
can be sustained across the resistor as well as from the body to
ground. I

To be on the safe side, bond the amplifier chassis and the PS chassis
together with a suitable length of shield from a piece of coax or similar
cable.
It certainly makes a big difference with the Hallicrafters SR-2000
Hurricane and P-2000 power supply. It is probably not a bad idea with any

There is a ground wire in the cable that connects to pin 7 on both
PS and amplifier that ties the chassis together. As I understand
the metering system of the L4B/L7 you will always have the high
voltage return sitting slightly above chassis due to the grid
