[TenTec] Fwd: Model 715 question

[Richards]

All quite right, Geoffrey.

I am just surprised that TenTec did not anticipate the more common 
computer type headsets.   A 1/8 inch mono jack on a dynamic set is 
hardly a common plug to find on headsets these days.   Contrary to TT's 
claim HEIL does not make this a common connector in its stuff, and I 
have plenty of headsets - broadcast quality to cheap comptuer sets, and 
only one has a 1/8 inch two pole mono plug -- the Shure HW-501 dynamic 
mic - but it has been out of production for more than 15 years !  (It 
does sound good on it, however... but it lacks earphone receivers... so 
it is difficult to implement  with headphones...)

Thanks for the web article reference.  I have read many such articles, 
but that is one of the most concise, clearest statements I have seen.

I still wonder whether I can replace the front panel jack with a 
three-pole jack and draw the required voltage from pin 2 on the 8-pin 
jack.  That would be an easy mod.

Happy Trails.
