[Elecraft] KSB2: Accidentally reversed RP2 - OK?

[John R. Lonigro]

Kristinn:
Looks like the resistor gods were with you this time.  If you look at 
the schematic for the KSB2, you'll see (upper right corner) that RP2 is 
4 separate resistors with no pins in common (1-2, 3-4, 5-6, 7-8), so you 
can keep RP2 installed reversed.  The same is true for RP1.  HOWEVER, 
RP5, for example, has a common pin (pin 1), so if you had reversed RP5, 
you would have had to desolder it and install it correctly.

Good luck with the rest of the installation, but watch out for those 
polarizing markings!  They are usually there for a reason.

73's,
