[TenTec] multiple rigs to one speaker?

Well, I see they still make the 2 speaker lines to 1 speaker transformer. 
That will take the speaker output from two rigs and deliver mixed output to a 
single speaker. 

Personally, too many years of handloading for very short barreled carbines 
has left my hearing a little beat up, so I use an outboard multi-input audio 
amplifier to mix the audio from the rigs and tailor the response to my needs.
