Well, of course any mirrored mis-wiring of the 9-pin socket would be a likely explanation. If it is correctly wired, then a failure of the tube heater to light up would be a likely (and easily checked) test.

ok thanks for all the help so far. all tubes are working and all the testing checks out except for two values.  #5 reads 60volts and #11 reads 0volts. have checked the manual and everything looks good, my only concern would be the 1.6k ohm and 47 ohm resistors. could they cause this problem. thanks paul
