I had the pcb produced by Jay_Diddy_B, and I ordered the components at lcsc, however I finished assembling everything and saw that it wasn't working.
After analyzing it, I saw that only the voltage next to Q3 - 2N3906 did not match, the others were ok.
Then I realized that the resistors r8 and r10, I bought in kilohms instead of ohms.
I can exchange the R8 for a 30R metal film resistor, but I can't find the r10 in any store in my area, the closest value I can get is 3.3 Ohms or 2.7 Ohms.
Any other solution, even changing resistors r7 and r9?
