[Elecraft] Rework Eliminators? OK?

[k4zm]

I'm wondering what plus & minus the "Rework
Eliminators" would buy me?



The Rework Eliminator does exactly what the name implies.  If you chose to 
install them at the time of building then you can add K2 options at anytime 
by simply removing the unmodule and plugging in the option.  It eliminates 
the necessity to tear the K2 apart an remove some components and install 
others.  With the KSB2 you have to remove the control board remove the front 
panel and remove the front panel circuit board from the actual panel which 
requires the removal of all knobs and then install the trnasistor a couple 
of resistors and several capacitors and a diode and the 16 pin connector on 
the back of the board.  This means soldering in so very tight quarters to 
install this connector.  Also it requires the removal of two jumpers and a 
.001 capacitor on the RF Board.  This requires that you remove the botom 
cover.  The Noise Blanker requires that you remove three resistors from the 
RF board and a jumper and reinstalling a resistor and a jumper.  The KPA100 
option requires that you install a power connector on the RF board in a area 
under the Heat sink  so it requires the removal and replacement of the heat 
sink which is a tricky operation and can lead to a shorted final transistor. 
The 60 meter option and the K160RX also require the removal of the Heat 
sink. The 60 meter option requires the installation of a couple of 
capacitors and a run of rg 174 coax and one end is connected under the Heat 
shield.  I have installed them in one K2 that I built for a fellow in 
Virgina and I highly recommend the instal of them at the time of the build 
if you plan to install the options at a later date.  If you plan to install 
them at the same time as you build the K2 then they are not needed as you 
can get the parts needed from the respective options as you build the K2.
