Hi everyone,

My Swede works (after taking the 120R out of R14 and putting in the correct 10k) however it doesn’t clip hard enough and is not very loud.

Using an audio probe, I get a unity gain signal at the jfet, a good loud boost at the 3904 (Q2) and the 3906 (Q3) however there is a huge volume drop between the collector of Q2 and the base of Q3. Specifically, it’s right where R11 (22k) connects to the base. Very strong signal on R11 right after C6. It seems like R11 is dropping too much volume. Any ideas? Basically, there is not enough gain from Q3 to get the diodes to clip. The sound is like an overdrive.

Voltages on Q3 look a bit strange, but it seems to be amplifying ok. I think if the base was getting more signal it would give me the boost I need to hit the clipping diodes.

C- 4.42
B- 4.52
E- 5.24
