Delta Pulse

[UFO]

That schematic is full of errors.

Hi kt315
please can you put here photos of shield the pcb and grounded falsepanels via resistors 100 Ohm ?
many thanks advense

hi raf33,

I am glad you appreciated my note. because the shielding is REALLY IMPORTANT for the stabile work. I did due like it is done in Deepers 10DD. here is fixed schematic - R59 R60 has to be connected to +12V like to Deepers. look my photos in Deepers thread, you have to notice the wires between the points at PCB and falsepanels. there is a shield plate under the PCB - look at photo. it is grounded directly to +12V.

Hi g.s
Is va meter when measured by measurement set in 1 ohms the va meter the cursor moves.

-Does it work and there's a sound only?

hi raff33 you can with help you at previous my question

[raff33]

please

About one unstability I did meet of and fight with.

On winter Delta worked only good, but now not I waste much time on a decision, but seems have got an answer. There is some kinda pickup from operator body. You have to shield the PCB. I did put a copper foil under the PCB, clued it to bottom of box and grounded by wire to schematic's (-E). I also grounded falsepanels via resistors 100 Ohm, those are aluminium done. Now DP works great.

hi jap it va meter works at yours pcb why my own i have problem please help

Hi apocalypto

Hi apocalypto
you must use a magnifying glass!!!!!!!!
bad pcb
Mistake is clear
you must measurement +12v between c31 =10000uf+,- Equal to between pin4,8
And pin1 .
Mistakes are terminals to develop measurement Because there is an a virtual GND=REF
In the case of lm555 Only
The negative terminal of the black color in - (pin1).
The positive terminal of a red color in + (pin4,.
if not Maybe the battery are damaged
-------------
Other like D5 (TL062)
The negative terminal of the black color in - (virtual GND=REF)

Hi freind Jap
1) I got 12 V between +,- of C31 = 10000 uF
2) I got 10,33 V between pins (1,4) and (1, of NE555

please JAP i used this pcb of bombaci (26.08.07 / Duzenlem : 02) is it a good PCB ? if i will made a new pcb what is the good ?

Hi apocalypto
This is a mistake in making pcb like short- and result a damage or measuring voltage xxrong
First 1-I advise using a magnifying glass and examine the worked PCB on the tracks or short welding tin
2- out 2 ICS from the PCB project D5 (TL062)+lm555
3- measuring the dots task, such as 2pin oe c31 =10000uf +,- , as +12V,pin4,8 of lm555 And pin1 so on ---

-----After this-- You get =+12v and then put them{2 ICS} one after one with the measurement the same dots every time you put one in order to know if one of them is damaged.

thnk's Jap
1) I hv'nt now a magnifying glass
2) i removed the 2 ICs (TL062 and NE555) as you said, when i mesure voltage at pin 1, 4 and 8 of NE555 connexion i got (-6,8 at pin 1) and (5,4 at pins 4 / .
3) I put the TL062 i got the same results of 2)
4) when I put NE555 i got (-2 V at pins 4 / and (-6,8 V at pin 1)

Hi everybody

I feel i'm near the solution to repair my delta pulse, i wld like to give you some details :

* I have the right voltage value E (5.4 V) at all the check points expect pin 4 of LM555 i got (-2.04 V).

* continued sound from speaker with or whitout metal near coil.
* D5 (TL062) become quickly very hot.
for information i have just a multimiter

please some advices
Cordialy

THANKS KT
i will check my DP
this your attached picture i have guestion
and the second picture which i made

[kt315]

THIS IS ALL TURKISH PCB LAYOUT.

[kt315]

Please can anyone tell me the voltage value of "E" ?
for me the value is 5.4 V it is right or wrong ?
cordialy

regarding ZERO-EARTH 5,4 is maybe right. regarding -12V you have to have +12 of your battery. +E=+12
