I have had four 3TF7  failures since 1973. Two were in radios purchased 
and transported by motor frieght. Four in Thirty plus years isn`t so bad 
.Hey,Hank ,what would you want for a couple more? I tend to agree with 
Hank.These radios were built to work under very severe conditions and to 
work 24/7.Both the R390A and R390 were /are supurbly designed radio 
recievers.73 Gregory
