[TenTec] Audio distortion in Omni VI(standard),

[k8vf_mark at centurytel.net]

I pulled connector 67 in the noise blanker line to remove the noise blanker 
control, in case the pot was shorted.

It had no effect.

In fact the noise blanker has litle or no effect at any time. I see that 
this was a common complaint.

Also pulled the pulse line, but it is apparent that the noise blanker is not 
causing the distortion.

It is not unreadable, just "there" and I wondered if anyone had experienced 
it? (and if there was a fix).
