[Harp-L] LETHAL VOLTAGES was: Low plate voltage on the preamp tubes?

[Dina Janzen <dlj@xxxxxx>]

I failed to emphasize the risk sufficiently.
Fender 6L6 amps have around 650 AC between the secondary windings of 
the power transformer
450V down to about 250 V DC in the power supply to the plates.
Touch the wrong spot at the wrong time and you could be killed.
