For some bizarre reason my TSA that I wired with a LED, SPST toggle and pot to switch from TB box to feedback loop is not working anymore. When I flick the toggle it won't oscillate. It only works as a TB box. It's a bit frustrating.
Any ideas on what could be going wrong? I rewired the toggle and pot to assure it wasn't a bad solid core wire, but it still isn't working.
Sounds like it's time to get out your DMM and see if the switch is working. Cheap ones have a nasty habit of failing.
If it's good, then just check every connection to see if they are connecting to where they should be.
Good luck!
Thanks for the response. I finally figured it out with the help of a diagram I had on my hard drive.
