So what were the big decision factors behind all glass, and the metal/glass
combo tubes....? Was it the manufacture of the bell that was hard to do in
glass ....? Was it weight...? Was there safety concerns about the large
glass envelop imploding and all the glass flying that made them wanna
use the glass/metal combo....?
In the ad it's just put out by US Steel, so it's obvious here that there is at
this time a choice in construction, and they are trying to get manufacturers
to consumers to ask for glass metal tubes for their industry.....
Was there consumer involvement in the sales - end use so to speak - ?
Did consumers ask for either design....? I know each company touted
the items they used as being the "better" of any choices they may
have made, and it would show up in their literature.... But did customers
actually have any preference...? I can't imagine it would have made much
difference....
Some of the tube radios I know did make it a selling point if they had a
high tube count.....
