Build Report: Burning Crunch (improved Krank D M)

[askwho69]

hi dschwartz ....i'm nubie here...

i just wanna ask, what is the main differ the lay out you've already post with this one...



i found some differ caps and resistors value on that layout...
thanks for the help before...

is this lay out here verified? does it works? thnks

9V is going nowhere on the latest vero layout.

9V is going nowhere on the latest vero layout.

i never built it in the end, there was too much fizz on the end of notes, a lot of people had this problem,

i posted that when i experimenting with it ok.....


ps. the 9v pin 6 should be jumpwed to the top rail yes!...i just never bothered after the noise issue.
ask around a few people had that noise issue too....

use shielded cables for signal. I got it working that way!
So: from Input to f-switch and to PCB.
From PCB to Volume Pot to output.
Use short wires. Don't cross output and input wires.

Finally I build this, but it wasn't what it should be (I think). There is a lot of gain but no distrotion. It's like slighty distorted overdrive. Also volume rolls down with gain pot.
I probe the signal path and there is just slighly gain after collector. Voltages are C:2,57V, B:0.79V and E:0.18V
What do you think?

I built this on a dorkbot fabbed PCB, my own layout.

Thoughts on how to reduce noise? Or just another problem of the 386?
