[Elecraft] K3 Buffer Mod

[N2TK]

Tnx Don,
I do have the correct values in 1/8w. I wouldn't think there would be a
difference, but I like to ask first, just in case.
Finally should get some time over the next week to get beyond page 25 of the
assembly manual for my second K3.

73,
N2TK, Tony

Tony,

Since this is not a high frequency area, there should be little 
performance difference (if any) between SMD parts and axial leaded 
parts.  The more relevant consideration is physical fit.  If you have 
1/8 watt resistors it would be easier than 1/4 watt, but you should be 
able to get the 1/4 watt parts in there.
