My Model 950 volume control is acting erratic; what can be done to address this?
Last Updated 5 years ago

I cannot recall ever having to replace one of these volume controls.

The issue with the rotary encoder(volume control) becoming inoperable, develops from a lack of use more than anything.
Like myself, most of us primarily use the remote control for volume operation. Thus, allowing the master volume control's internal contact surface to become oxidized.

The solution for this, is to remove the front panel assembly, disassemble the volume control and clean off the oxidation from the flat surface of the rotary encoder.

First, the following will help you in the front panel removal...

Start by removing the top cover, then the front panel assembly can be separated by removing two screws on each side along with three on the bottom. Unplug two cables from the main board and lift the panel assembly away.
You must then separate the board from the front panel by removing all the black screws, along with the nut fastener from the volume control.
The control on the front panel board can be separated by bending the four tabs that hold it together, removing the stem piece, wiping off the lubrication and [using a pencil eraser], cleaning the oxidation from the surface. Then reassembling the control, and front panel assembly. Don't forget to add new lubrication.

Reverse the procedure for reassembly.
