[Elecraft] K2 Resistor question...

David,

Most all the resistors in the K2 (including R20) are 1/4 watt. The only 
  1/2 watt resistors on the RF Board are R50 and R58.

To the best of my knowledge, all resistors shown in the schematic that 
are NOT 1/4 watt are designated with the power rating.  In most cases, a 
1/2 watt can be used as a replacement for a 1/4 watt resistor, but the 
problem is in the physical mounting space - if you can get it to fit all 
will be well.
