Safe to powerup without Speaker?
#14

I'm wondering, usually the soldering part would be virtually done before you put power to it so I would do everything I need to do to it that I can see, then take it upstairs and hook up to the speaker to check voltages and do the alignment. Also, if you need to do a simple solder, you cant bring up a soldering iron and mat to make a small change if needed?

The previous owner had changed the electrolytics and about half of the paper capacitors so I figured it was safe to power it up.  All i could hear was a load clicking noise so I completely recapped the radio and replaced all the  wires with bad insulation.  It still sounds exactly the same.  I do have a disconnected wire that I can't find on the schematic.  The previous owner labeled it "GR" which to me could me ground or green (it appears to be a white wire with a green tracer).  Here's a photo of my mystery wire.
Could this be my problem?  I know my LO isn't working as well since I couldn't hear it on a nearby radio.  I confess I still have two micromolds I haven't replaced yet one is a 5300pf and the other is a 3300pf that I can't find on the schematic.  I have another wire that I can't trace and that's the one that's between the red and black antenna wires (third screw from the left) it's unconnected as well.
Thanks,
Keith
