[TenTec] Omni VI & 960 Power Supply

[Stuart Rohre]

The raspy speaker in the power supply upon warm up sounds like warping of
the speaker frame due to heat and unequal mounting bolt torque.  Try
loosening all the screws on speaker and then tightening just snug, while
listening to it.  Heat over time might have warped the voice coil, and in
its throw, it is dragging at a point.

If you cannot find any suitable torque, try another speaker temporarily next
to the faulty one.  That should resolve any RF issue.  Do not overly torque
speaker mountings especially when mounted in a cabinet with a heat source.
