YJM 308 oscillation

I finally figured out the problem.  I was running the output into my breadboard  which is how I connect to  a 1/4' jack.  The breadboard was causing the problem.  I disconnected from the breadboard and used a jumper wire to connect to the jack and the squeal went away.  There never was a problem with the actual circuit board.  :roll:

Another problem solved  and if this happens again I have a new place to start troubleshooting.

Thanks again guys for all of your help.

I also got my TS/Landgraf going tonight as well.  It fired right up.  It always seems I have more problems with the simple circuits as opposed to the more involved  stuff.

I'm glad that you got it worked out.
