Project: Stage Fright
Issue:  Signal going through unaffected.  Speed LED works great.
5/6 switch to the right.  
Speed and Balls about halfway.

The only sub is for R48.  I used 2.7k instead of 3k.

Voltages:
At power source: 9.16v

Three random spots:
Switch lug next to "5/6": 2.233v
R27: 4.42v and 5.58v
C3:4.57v

3. going nuts
4. .3mv
5. 4.58v

12. 4.56v

I can't find any sort of pattern in these, like I thought I would.  I can only describe these as bat shit insane.

So, eh...what's up?

Answer: Jumper the CV.




icecycle66

Crap.

I didn't jumper the CV.

Well, notice anything else amiss while this is up here?

eldanko

Ever get this figured out? Mine's doing something similar...

icecycle66

Yeah, I didn't jumper the CV.

Check that out.

eldanko

Yeah, I neglected that step as well... but still having problems. I'll do some debugging and post a thread if I can't figure it out. Thanks!
