[Hallicrafters] High Voltage Hazard

I try to keep in mind that Ross Hull, the Australian Ham who came up 
with the 1929 High-C Hartley transmitter circuit and many others, died 
when he got across the HV of an experimental TV receiver he was 
demonstrating.

I have been 'bit' numerous times when I got a hand between my Cannonball 
"Dixie" headphones (terminals at plate potential) and ground.  Somewhere 
back c. 1928(?) in QST there is an obit for some well known Ham of the 
day who actually died that way.

Can't be too careful!

Wishing long life to one and all,
Rich, KC9GQ
