[Philco47]

Hello All,
I am working on a Philco 48-1270 console.  I replaced all the capacitors, all but 2 resistors, and the electrolytics, I didn't touch the Mica caps.  AM, FM, SW all work well no hum at all, they have their own electrolytics. As soon as you push the phono push button it hums like a bad electrolytic.  The turntable plays, you can faintly hear it under the hum. It hums when the turntable is connected and disconnected.  So the problem is in the chassis.  
It uses a 7AF7 as the phono amp. - phase Inv. tube.  If you pull the 7AF7 tube the buzz stops, but so will the phono output.  I traced out every wire and connection from the 7AF7 socket and see no problems.  I tried 2 different tubes, getting the same result.  I had replaced the original 10mf electrolytics (16 A & B on the schematic) with new 10mf electrolytics with a stronger working voltage. The phono push button is not shorted.  I'm stumped.
Should I boost the 10mf a little higher?  Triple check the 10mf for errors? (A safer bet) Maybe have 2 bad 7AF7 tubes?
Any ideas are welcome.  
Thank you,
Steve
