[Milsurplus] VT-4/211

[Bruce Gentry]

Inexpensive VT-4s and 864s kept many older  amplifiers in struggling 
movie theaters going into the early 1980s. The newer and larger 
amplifiers used 845s in the output, I can't recall them ever being as 
inexpensive as VT-4/221s. Many of the theater amplifiers used VT-4s for 
the rectifiers, with the grid and plate connected together. I have heard 
differing opinions on using tubes that had seen service as rectifiers 
for  amplifier positions.
