[Hallicrafters] HA-6 and HA-2 transverters

[Larry]

On the subject of transmitting converters, some years ago I picked up a 
little 6 meter unit made by Continental Electronics called a "Six".  
It's about a foot square, gray, and has a 2E26 output tube.  The power 
supply is external (which I had to build my own).  A odd feature is that 
it needed a 22 1/2 volt bias battery (I used two 9 volt batteries in 
series).  I made quite a few SSB and CW QSO's with it.

I was interested in it because I had never seen or heard of one before I 
stumbled upon it.  I had no idea Continental had ever build any ham 
gear.  It is marked as being made in Sumter, SC which is about 25 miles 
from where I live.  I know Continental manufactures high power short 
wave transmitters for the commercial market but not around here.

I never found a manual or schematic for the beast and had to de-cipher 
it on my own.  I guess my question is:  Has anyone ever seen one of 
these and know anything about the history of it?

Thanks,
