    ST-70 Bad Output Trans? Empty ST-70 Bad Output Trans?

    Here's what's going on. With NO tubes installed except for the rectifier, there is a popping sound out of just one channel once the voltage comes up. I checked the transformer with an ohm meter and all reads OK. Has anyone ever experienced anything like this?
