K2: Suggestions wanted on slightly hotrodding an early S/N K2

[Allan Taylor]

I have recently purchased a very early K2 (S/N 152) and would like
reasonable suggestions on how to up slightly the output of the PA
stage. Recalling from way back when
I actually built a K2 (S/N 157, subsequently sold), the available
drive was affected by winding of toroids, selection of driver
transistor etc. I can't go class C as I have the
ssb module in the rig.  My goal is to have the power level of the
Tentec Argonaut V but with the K2 receiver! My interests are entirely
portable/backcountry use.

Allan,

You will not be able to achieve the 20 watts of the Argo V with the K2.  
Expect 12 watts to 15 watts depending on the band.

The winding of T1 and T2 are important to the power output on the higher
bands, especially T2 which should be mounted about 1/8 inch above the
board for best results.  See the winding details in the new manual.
