[TenTec] Heil headphones

[Duane Calvin]

My Orion 1 has the same problem reported in the original posting.  I have to
run the AF gain at about 75% when driving my Heil ProSet, and unplugging the
earphones causes the internal speaker to really blast since it only requires
about 30% AF gain to drive it fully.  I'd also like a solution without
losing the Heil ProSet, which I really like.

Does  anyone have a method that matches the output of the Orion 2 to the
Heil Pro  set earphones.  I believe the O2 has a 600 ohm output and the
headset  is 8 ohms.  I tried using two of radio shack 1000ohm to 8 ohm
audio  transformers, but that didn't seem to work, unless I did  something
wrong.  I used two to try to use the stereo feature of the  O2.  I have
the rf mod in also.

I don't like unplugging the  earphones and having the audio blast into
the room when I forget to turn  down the audio gain.

Any help would be appreciated.

The headphone output of the Orion II is 16-32 ohms. I have two Heil  
Pro-Sets, a Heil BM-10 and a Heil Quietphone. They all work fine directly
plugged 
into the front panel headphone jack.
