NN1G Problem

Ok, all of you technical wizards out there. Here is a problem for you from
a non technical builder of the NN1G. I put the kit from Danny Stevig together
this week. The first thing that you are supposed to do is to test for audio.
I plugged in the phones, and the power, and nada, nothing, even adjusting T4
did not help. So, I used the Dougie method of touching various parts to see
if I forgot to solder a joint or something (not unknown to happen). Well, I
accidently shorted the heatsink on Q7 to the case of Q6, and bingo! tons of
audio. So I separated the two, took a clip lead and tried it again. Worked
fine. So, what is my problem? Do you have an idea of what it could be? The
schematic is in January 93 QRP Quarterly or September QRPp. I would appreciate
the help.
72, Doug
