I just got a used Harmonic Tremolo (it looks brand new). I'm having an issue with the speed. If the Speed knob is at 9:00 or lower, the tremolo quits, although the signal passes through to the amp ok. If I turn the pedal off and then back on again, the slowest speeds will work, but only for about 10-15 seconds. Any ideas on what is wrong?

Maybe they mixed up one of the 2N3904 transistors with the 2N5089. Maybe they mixed up the cap or resistor values in the LFO. Pics would help.

Please make them LARGE, well-lit and well-focused, so that we can see the detail needed to determine of anything is misplaced or otherwise visually wrong.

You can post using the Tapatalk app, but it has a poor record on privacy. I would recommend uploading to Imgur or Dropbox or Google Drive and providing links from those apps. We can then edit the post for you to show the images inline.
