Last March, I was trying to figure out what's wrong with this old Crosley chassis.  I'm getting no output, but also no hum, just a little static when I turn the volume up or down.

Thomas Albrecht and several others of you were gracious to help me figure it out.  I'm now back to that project and have determined the following:  All voltages on all tubes are within or close to spec, except for the 6SQ7, 1st detector stage. 

The readings on that tube are pin 2  -1v  (and I do get a little hum from the speaker when testing).  Pin 4  -1v  Pin 6  75v (should be 110)  Pin 7  6.3v ac

All other tubes measure spec or close to it.

Being a novice at this can you tell me what I should check next?  Keep in mind that I'm just learning and don't have any test equipment besides a Simpson meter and a Precision tube tester.


Thanks so much,  I haven't been in touch with the forum lately, but will try to be more active.
