Zero Point DD

[Tcheloviski]

(1) Project Name: Zero Point DD

(2) General description of the problem: i get only Clean sound and Tick Tick Tick.
Power Regulator Very Hot.

(3) Steps that you have taken to try to resolve the issue:
Checked Wiring 10x or more

1 - Change the pt2399
2 - Change Transistors BC550B
3 - Change Power Regulator
4 - Change Position Of Transistors
5 - Change BC550B For BC108
6 - Change BC108 For BC550B
8 - Change TL072
9 - Check Diodes Position

(4) List any substitutions you used for parts/values
No Subs

You have a short connecting the 9v to ground somewhere.

[Tcheloviski]

the board have 3 grounds.

2 for 9v
1 for PCI Grounding

i connect 9V Ground in tip
the 9V+ in 9V

All Grounds in rig of input

Correct?

i'm holding for doesn't take a hammer and destroy the pcb

Coca cola time.

Ground = common -- all ground points in a circuit are connected together. It sounds like you have that correct.

The tick tick tick sound you've described would be caused by the +9v being connected to the ground. Use your multimeter, on the continuity setting, to see if the +9v is connected to the ground (it will beep). They should not be connected. If they are, then that is the problem you need to fix.

Pot Problem?

[jimilee]

Sounds like a ground issue. How are you powering it? Have you taken any voltage readings yet?

Solved TODAY 

Just change The IC and one capacitor.
Sounds nice.
Thanks!
