Need to use Workbench HD for the James Tyler Variax.

Line 6 authorized service tech near you should have the tools to do it. https://line6.com/find/service_center/

Contact Line 6 Support on that, log a ticket in your Line 6 account, they might be able to answer that question for you. Don't know how backwards compatible it will be for earlier pre-HD Variax guitars.

As far as I know, the DigiKey supply is NOT a 'drop in' replacement. Use at your own risk. Just remember, that any modifications that alter the unit function may and can void any warranty. If something were to go wrong and it ends up on my repair bench, chances are I'd have to send it back untouched. Just so you are all aware.

Do not use v1.8x,... there was glitch in it where, if you tried to update later from there, you have a 50/50 chance of locking up the program board (bricking it), making it non functional. At that point, I would have less than a 50/50 chance of bringing that board back to life with the tools I have here at Line 6. So Do not use v1.8x.

Download to your computer desktop and update from there. Monkey is no longer on the Line 6 server. You can download it to your computer and use it as a stand alone app.

Check the Downloads page on the Line 6 site for computer OS compatibility for the update you are trying to do.

Loose chassis ground on a pick up or the bridge, loose connector not fully inserted are the prime suspects.

Noise like that is typically due to a floating ground somewhere. A product that old may have a number of oxidized intermittent solder points or a loose connector. Have a Line 6 authorized service center check it out.

Don't use the Line 6 Server, update from your local C-Drive on the computer. Download the Central , then download the Firmware (v2.23). Connect Variax to computer as you would for an update. Open Central and sign in, make certain "My Computer" comes up as "Authorized", and your Variax comes up on Central. Click on the Variax and an update window should come up. There should be a virtual button that says "Update from File", ... click on it. Find the TylerVariax_2.23.vxf file and update from that.

Don't have that info on hand about the original ratings. Super old product so that is probably buried deep in some archive. Vacuum tube SVT would be pretty substantial cable, as tube amps pull a lot of power. Same criteria would apply.

Best bet is the 105 C cable for something like that. Bigger diameter means more insulation means it can handle more heat. So chances are the bigger diameter and 105 C would be the better cable to use.

Have it checked out by a Line 6 authorized service center. Buttons, pivot underneath, solder point on the UI board, interface cable between the UI and processor board,... an authorized service tech can check it out. https://line6.com/find/service_center/
