[ARC5] OK Smart People - Mystery 211s

[David Stinson]

Just finished testing my stash of 211 transmit tubes 
by putting them in the BC-375.  
More than half were bad- mostly gassy.  sniff....

Anyways, here's a mystery:  A few would not 
draw much current or put out much power in the
PA stage, but they seem to work just fine
in the Oscillator stage.  If this was low emission,
I'd think they'd fail in either stage.  As a result,
I've got four tubes marked "OSC ONLY."

What's up with this?
