[Hallicrafters] tube shields

[Richard Knoppow]

    I have some EIRC (is that correct?) heat dissipating shields 
that push down over the standard bayonet socket skirts. That is 
what I was thinking of. The sides are slotted with  the holes for 
the dimples on the socket toward the bottom. The springiness of 
the shield holds them on. I don't know what could be different on 
the socket skirts (I don't know the correct name for this part) 
for the push-on type shield. OTOH, despite my ancient age (I 
think there is a bourbon by that name) I don't remember ever 
seeing any sort of special sockets. Doesn't mean there aren't 
such things. I am continually amazed by the stuff that's been 
around forever that I never heard of. Maybe a couple of pix would 
help.
