I finished restoring this nice model 16 Tombstone. It has a tone coming through the audio much higher than power supply hum. I would describe it more like an audible note or tone. All Bakelite blocks recapped, New filter caps. There were a few dog bone resistors out of range so I replaced them. The radio plays fine otherwise. Shadow meter works good. Alignment went well. Any ideas would be appreciated. Thanks, Mike.
