1st question, just starting...

Jeff Kinzli
Hey folks...I just started building K2 #5945. Can't wait to get back
to the bench :)

As I was going through soldering the first few resistors and resistor
packs, I looked at my solder job through a magnifying glass and
noticed that it *looks* like pins 2 & 3 and 6 & 7 on RP1 (on the
control board) are tied together. Is that true? Electrically they are
now and as I pull more solder off it appears that it's meant to be
that way, but looking at the schematic, I'm not seeing it that way.

I know I'm missing something dumb, but I'm hoping someone will set me
straight and I can move on :)

Thanks for any  ideas.

Jeff

Jeff,

My schematic shows one connection for pins 2 and 3, another for pins 6 and
7, and yet another for pins 4 and 5 (that is what the comma between the pin
designations indicate).

So yes those pins are normally tied together.  The problem is usually
created by a short through a solder bridge between pins 6,7 and 4,5 - that
short usually occurs at the end of resistor RE near pins 4,5.

Don W3FPR
