galaxy dx99v variable power unresponsive

[jef]

The variable power knob on my galaxy is not doing anything I set the internal am high power pot vr13 to 4 watts swing to 8 but I cant get the knob to adjust watts tried turning knob down to adjust vr16 low power but it doesn't change is stays at 4 watts dead key,all wires appear to be hooked up to knob but not sure where else to look to get my variable power working.

Not too many choices. A broken connection to the front-panel control, a bad control or bad VR16. If VR16 fails as an open circuit, it will disable the front-panel control.
