I SHOULD be embarrassed by my mistakes...but, I figure, I am learning  
more electronics in the last few months than I ever did in my early  
years.  So, I really don't mind sharing them with the group.  Hope  
the group doesn't mind.

Here's the latest news:

Yes, as noted before I found errors relating to confusing 560  
designation and 561 and 820 designation and 821.
I found the "evil twins" tonight: C228 was a 561 (supposed to be  
560)  and C210 was a 821 (supposed to be 820)

So C4 is now correct (821) and C12 is correct (561)
I will get the right caps for C228 and 210 and start alignment over.

Now, as I was reviewing solder joints, etc., I noted that one of the  
solder pads for C4 was touching the outer can tab of L1.
My question:

Is this a solder bridge, or is there supposed to be a connection  
between C4 pad and outer (ground) tab of L1?
I looked on N0SS's PCB pix and I cannot tell if a connection exists  
there or not.  (thanks, by the way, to Tom for the pix).
