Hello,
Where can I find the schematic diagram for MK172. There is not such diagram in manual (why?, in other kit e.g. crab was present). I have yesterday made (soldered) Sound Star VU meter, but something is wrong. I had powered circuit with 9V battery, but VU meter did not work. I found voltage on DC connector and Switch, but on Zenerdiode was 0V!
Without diagram (and black painted board) I can not found fault.

Best regards! :question:

It is not in the manual for the simple fact that there was no room for it.
You can find it here:
