Hi Dave, congratulations on your SRR series receiver. I always thought they 
were straightforward to work on. Everything is laid out in a straightforward 
logical manner. You can troubleshoot each stage if something goes wrong. The 
tubes are a little harder to replace but they can be tested on many of the older 
tube-testers with subminiature test sockets on them. You have to remove the 
rear filter assembly from the case in order to power up the radio outside of the 
slide-in case, but it only takes a few minutes to do that with a screwdriver. 
Main horrors would be if one of the RF/IF coils shorted or went bad. They are 
sealed in epoxy and impossible to repair. Also would be bad news if the 
mechanical filters ever went bad if you have one of the "A" models. Only thing you 
can do in those cases is have another receiver you can take apart for spares. 
Good luck. 73 Todd Roberts WD4NGG.
