Mic/Line Button

[Dreamsequence]

Does anyone know for a fact whether the button cap for the Mic/Line switch can be removed through the faceplate without disassembling the entire console? It's not hinged like the momentary contact pushbuttons. I have one unit that needs a DeoxIt bath.

Thanks.

If it's like the transport buttons and I expect it is, it comes straight out.

Yes, you can remove those without tearing into the console.

Thanks Crash. Time for DeoxIt.

Also, have one V-pot (Monitor Volume, what else?) that is being a bear. I'm going to pull that knob and try some a canned air duster, but I don't suppose they benefit from DeoxIt. Any suggestions?

You might look into the database in regards to the volume knob. I think there have been some that have given the volume knob the deoxit treatment which results in the knob feeling different in the way it spins for a time as I recall.

Thanks Crash. They do pull off through the faceplate if you take your time. I achieved some success with a DeoxIt needle applicator, but these switches are sealed better than the typical stack switch.

I checked the schematic for the v-pot connections, and it does appear to be a mechanical encoder. It consists of a resistive surface with a wiper. There are (2) stacked in each pot so the direction of rotation can be determined. The LED driver IC then knows which way to light the display pointer around the knob. I tried isopropyl alcohol and the air duster, with marginal results. Because it is a regular resistor (at least in the schematic), the DeoxIt might help.

Nothing ventured, nothing gained...
