Hey everyone, I have been trying to debug this for a couple days, cant seem to find the problem, Im posting hoping someone could help!
So first of all Im using a great John Lyons PCB, checked for cold solders, solder shorts and everything is clean and conducting. I have audio probed it an past Q1, I get some sort of faint signal that is sort of stuttering very fast, that could be explained by the voltages I posted below. So am I wrong or should all Jfet Q's should have at least 4.5 volts in to "open"?
Here are the voltages and Q types:
Q1 2N-5952 D: 8.97v G: 4.55v S: 3.22v Q7 2N 5088 C 4.82 B:.60(mv) E .40(mv)
Q2 " D: 4.71 G: 2.82 S:1.48 Q8 " C:8.97 B:4.84 E: 4.31
Q3 " D: 5.09 G:2.56 S:1.43 Q9 " C:6.67 B:2.77 E: 2.30
Q4 " D: 8.97 G: 4.44 S:3.36 Q10 2N 3906 C:8.97 B:8.31 E: 9.07
Q5 " D:1.16 G: 1.16 S:-(minus) 72.7
Q6 " D: 1.16 G1.16 S-(minus) .49mv
thanks for the help
