TSA troubleshooting..(I made a version with LED, SPST, pot)

[zenpeace69]

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.
