Zenith 10S690 Volume Control Issues

[vortalexfan]

OK so now I'm getting some static sounds out of the tuner at the spots where the stations would be coming in at but still no audio or reception.

I tried wiggling the tubes you suggested I wiggle (the 6A7 and the 7G7 tube) and it didn't make much difference.

So another question, can having the chassis not being completely tightened down to the cabinet cause reception issues?
