Hi,

I am pretty much in agreement, too. I have been fortunate enough to 
acquire a half dozen of the command receivers that aren't too badly 
hacked up. I'm only interested in actually using them on the air. Had to 
pay attention to ancient, leaky caps (not all of them are bad) and out 
of spec resistors (not all of them are bad). I have power supplies other 
than the original dynamotors that connect where the dynamotors used to. 
Sometimes I operate them from a battery supply. Some of the 
modifications have been reversed. I like using them the way they were 
designed. I am making homebrew "control boxes" to operate some of them 
through the same connectors those valiant young men used when the radios 
were new in new aeroplanes. When that project is completed more of the 
mods will be reversed. The receivers themselves don't need modification. 
There are no product detectors added or any of that stuff. I have 
*other* radios with newer circuits and I don't need them in the command 
receivers, too. I have been using audio DSP to help sort out the signals 
on a busy ham band. The DSP lives *outside* the receivers.

As others say - YMMV.
