Also:

A neutralizing tube is supposed to be a GOOD COLD TUBE. That is, if a bad tube is to be used for it, you have to be sure the reason it failed was the filament/lack of emisson and ONLY that. No other reason, like a short, crack or anything else.
It has to be otherwise perfectly fine tube without the heater.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
