Hi,
I just finished up the Seamoon Funk Machine V2 with the buffered blend.
Well, how the header says, iit doesn´t work, there is no sound coming out, but a faint hiss if I rotate the Blend knob towards the wet side.
I trieds to probe it, but I don´t really know if I do it correctly, I get a sound at the Output B (pin 6) of the LM1458, thats it. The side A on wich the NPN is doesnt work.
I measured every component prior of building it and everything was fine.
I checked for little bridges and went over the traces with a knife.
I used LM1458N, 2N5457 for Q1 and Q2 and 2N5088 for Q3.
Here are my voltages:
IC: Q1: Q2: Q3:
1: 4,1 D: 8,3 D: 8,3 E: 0
2: 4,2 S: 7,4 S: 7,4 B: 0,6
3: 4,1 G: 7,5 G: 7,5 C: 0
4: 0
5: 0
6: 6,2
7: 7,5
8: 8,3
The voltages of Q3 look weird, other than that I have no clues what is wrong
Thanks in advance for any help.
Cheers
