Hi, I’m David from Spain.
I received today a second hand Wiggler that basically doesn’t work.
The rate led is on, the signal goes clean through it but you can’t get the effect.
I tried with the original power supply, the one from English Muffn, replacing the bulbs…still the same.

Pressing the switch does nothing, you only can get the effect when you press the enclosure in a way that it’s in contact with the pcb. It this mean that It’s a ground problem? You also can get the effect by pressing down the input cable or connecting and disconnecting the input/output cable. By the way, It makes a horrible sound, It can’t be a good sign.

Well, please take a look to the attached video. It includes some pictures of some suspecting points of the pcb (I guess It maybe was “fixed” before)
If you can post photos of your wiggler guts to compare with mine or help in someway, I’ll be very very grateful.
