I found that the wall wart on my Chandler Tube Driver is getting sketchy. When I hang it from the wall with the tongs on the bottom I get connection, if I hang it so they are on the top, they do not. My thought is that I'll replace the wall wart by removing all the cabling for power and put in a socket/jack in the back and get a separate wall wart which will connect to the new wiring I put in (like most other 9v type adapters). But I know the wall wart is rated at 24v. Any input on this? I do not plan on selling it so as long as I can keep it running I will keep it. It sounds great and it's great for recording through my Blues Deluxe. Any good supply places to get the parts? Thanks all!
