[Elecraft] K1 amp keying circuit

[Don Wilhelm]

Denny,

Yes, it is really that simple.  I am not sure about your "plug it in" 
statement, if you use a connector at J1 on the filter board, you will 
not be able to plug in the KAT1 - so you may want to look for another 
place to pick up the 6R signal and 6 volts.

I've researched the archives and found some messages from 2008 and 2011 that indicate small 2 transistor circuit similar to that for the K2 could be used, driving it with the 6R line.  In reviewing the K1 RF Board and Filter board schematics, it looks like J1 on the filter board has everything I need - 6R, 6 Volts and a ground.  Just build a small board that could plug directly into this.  Can it really be that simple, or am I missing something?
