20k pot for echo-matic

[school]

where can i find a 20k lin. pot? mousers site is down, and the parts page on this site says they dont have 20k's anyway, smallbear doesnt have them, what am i to do? one other simple question: on this schematic http://www.moosapotamus.com/Echo-Matic_a.jpg , what is R5? 100 ohm?  it just says 100 on the parts list, anyone know what that is? thanks!

Just use a 25k pot.

9 times out of 10 ( unless its a mistake! ) a resistor without a "k" on a schem that has all others marked thus, will be in "ohms"  or "r"
I not, your value will be wrong by at least 1000  !!
