[TenTec] Omni VI Audio level spread.

[Steve Hunt]

Mike,

Thanks for the useful tip.

The Omni VI I bought recently had a "shot" AF gain pot. The track had totally worn at the "8/9 O'clock" position where all the action happens. Fortunately the guys at TT still keep the spares, although I wouldn't want to do the swap-out a second time - far too much trouble taking the front panel off :)

Spreading the "action" with your mod would reduce the wear and hopefully prevent it happening again.

73,

  On every Omni VI   I have had, the audio pot is only useable over 10% of its 
  range as it is way too loud.

  I needed to check out some new filters and had the bottom off of the Omni 
  VI,    SO..........


  I put a 70 ohm , i/8 watt resistor between wiper and af min on audio pot at 
  connector 55 on Lower pot board.

  Did this on Lower pot board as it was easiest, you could pull the if/af 
  board, too but I did not.

  Flip rig with bottom off and front toward you.

  Lower pot board is on right front...connect 70 ohms(or so) between 2nd and 
  3rd solder trace counting from the left.

  Works like a charm. Normal audio level is at 12 o clock now instead of 7 o 
  clock........
  I didn't have to pull any  boards either.

  I can only guarantee this on my rig, not responsible for yours.

  Best regards.
