[NJARC] Radio Repair Questions

[njarc@mailman.qth.net]

"matched" tubes are usually not truly matched, but  approximately equal in 
transconductance as measured on a tube tester. They probably never stay 
"matched" very long. For the purpose of  getting the GE to play It is not at all 
neccesary to match tubes. Depending on the heater voltage your "?" reading on the 
one tube may be meaningless.  If your radio sounds garbled or distorted you 
will want to check that the tubes are ok  by substituting them with known good 
ones before tearing into the circiutry.
