I recently finished building TM MII and was super excited to use it, but whatever I do, I can not manage to calibrate it.
When I patch a square wave to clock input, nothing is happening, there is no sound, no light movement on the leds at all.
I checked the resistors (replaced 2 that looks suspicious), capasitors and solderings. everything looks fine. I changed the amp chips (TL074 and TL072) and still, it's behaving the same.
Without calibration, I tried to use the module to see if everything is working or not. Clock input accepts clock, leds are working, all the outputs are working, but of course there is no magic is happening without the locking and randomization. I tried to do calibrate without hearing the voice, checking every time the randomization and locking working or not but it seems an impossible task
Is any of you experience this kind of behaviour? And could I ask, how did you solve it?
This is my second build, I am still a novice but I was super careful with everything. It's a bit disheartening to experience when you can not find what is wrong with it, since everything seems to be working, except the strange behaviour on the calibration process.
Should I try to change the other IC's? I was super eager to have this wonderful module, but now I am feeling a bit frustrated.
Any leads would be appreciated a lot.
Thanks in advance, all the best.
