John:
Don't use the pictures for this, use the schematic. There you'll
see that one end of C4 is grounded, as is the can of L1.

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).
