SOLVED Parentheses mini, no boost

[Markk]

Hi, I'm having a problem with the boost side. I have nothing, r32 is not working, I tried replacing the bs170, still nothing. I'm lost.

Going to bump this, also having a similar problem.

Haven't replaced the bs170 yet, but I get signal from the input to c21, but I don't get it on R27 or R28, which is weird (and signal stops at r28). Have continuity with ground on everything in the boost circuit, and continuity from the boost output all the way to the negative side of c23.

I'm going to double check my resistor values and try replacing the bs170 next time I order some parts, but any ideas on what it could be? Could a bad bs170/voltage affect upstream signal at R28?

Mine turned out to be a wrong resistor value at r31. I put in a 470k instead or 470r.

I've seen some other people have that as a problem as well - I did a quick check of the color band to rule that out, might be worth just replacing it to be sure.
