Stereo Separation - A properly working stereo tuner will have minimal crosstalk between the left and right channel.Ħ. Dial Tracking - How accurately the tuner dial or display indicates the actual frequency of the broadcast being received.ĥ. FM Mono Reception & Tuning Meter FunctionĤ. This device, in conjunction with an oscilloscope allows us to properly evaluate the following parameters:Ģ. ![]() The SG80 allows us to “simulate” an ideal radio station using precision test signals instead of music. If the unit passes visual inspection it is bench tested for a handful of key performance parameters using a Sencore SG80 AM/FM Stereo Analyzer. ![]() These parts are inspected for smooth operation. Vintage analog tuners also have moving parts related to the tuning gang and dial string. On vintage units we often spot check select capacitors for value and ESR. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Kimber Kable - RCA Interconnects - Better
