Ts4d Motorola

[timmy]

There is a component marked cr-1 it's rectangular with 4 legs and is mounted between the audio amp and output tubes. Is this a dual capacitor or a resistor array, I can't find a schematic with the parts list to identify it. Still trying to find out what's wrong with the audio why it's got a hum. From what I found is that the ts4d was the only chassis that had this component.
