Hi all,
I'm kind of a newbie to the radio restoration game and ran across a slight issue with my most recent acquisition, a 37-630 radio. The radio had a very loud hum which was eliminated after replacing the capacitors. However I was still getting no reception. Upon inspection of the wiring, I noticed two small black wires coming out of the 1st I.F. transformer which are not listed on the schematic. The coatings on these wires were cracked off and the wires were disconnected. It appeared as if one may have gone to ground and the other to somewhere on the 6K7G I.F. tube. I removed the can on the I.F. transformer and found that the wires went to the center of the middle coil. Anyways, could somebody please tell me where these thin black wires should be soldered to? Any other things I should specifically look for on a 37-630 for no reception?
Thanks
Dad
