Yes ... used to do that with 4-1000s back when ... could get as-new pulls 
from local TV station in the 60s - 70s  !! According to them, "dead" --  
actually had re resuscitated  some of them multiple times ... The usual 
pulls from the station were really lame, as they moved them from video to 
audio finals, and were plumb worn out ... the "dead" ones were much newer, 
when "fixed" --- lots more gain!
