Skreddy Pig Resistor Value ?

[Soup39]

Building a Skreddy P19 on an APIS SWARM PCB.  R19 is listed on Juan's terrific Muff doc as a value of  18k.  I thought I had some of these resistors  in house (sadly i don't). 

Not wanting to p wait on an order for a single resistor, am I better subbing in a lower 15k or  a higher 20k.  Or does this minor difference matter?

Don't know, but if you really can't wait, why not order some 18K's and build it using some socketed resistors?

agreed, probably the easiest thing to do.
