Zombie chorus with anti tick mod 1590b layout?..

[Perrow]

Found the problem with the Zombie, 220nf that should be a 220pf. Sweet chorus, the chips are good.

[Perrow]

Slightest of ticks with the amp (not the best of amps) dimed, but a good deal of noise with unshielded cables and flourescent lighting, so some ticking might be masked.

@#$%, i run out of solder....could've sworn i had a few rolls...arghhhhhhhhhhhhhhhhhhhhh....i'll still try reflowing

@pelle:  does it tell the time?..

[Perrow]

I know this thread has been hijacked into a Small Clone debug thread, but I persist in posting about the Zombie Chorus and can finally present a verified layout for it.



@d'Astro: No, but I excpect it to explode any second now.

[Scruffie]

set the trim, now 5.5v...so iknow the trimmers ok now..

i'll whip the ic's out and try reflowing the solder and see how it goes....cheers man!..

btw,the cat looks petrified now!..

Lol, what is it with your cat!  

'ang on, just noticed the voltages did change with the 3007 removed, must be getting confused...

Anyway, yeah try some reflowing of everything and then we'll see how things are progressing.

Which schematic did you build from? Might be able to cure it with a few mods.

@ pelle.cool, at least we know those chips are fine too!..


reflowed , nope!...

re: my cat!... ha ha ha...

The layout from the first reply to this thread.



But I stuck a TL062 in there for the LFO.

Just checked over the board comparing it to the tonepad pdf, and missed that one For what it's worth I couldn't find any other issues, looks good to me. I've corrected my layout but I'll hold back on posting it until we get this one going. I'll probably get time to try mine this evening, just have to remember to swap that cap.

[deadastronaut]

cool, i just have today/tonight to get it going, as i'm off camping/drinking this weekend...

ive double triple checked/compared, microscopically checked all traces/joints...might pull out the trannies and swap em....

[Perrow]

I just compared the BOM from my project with the Tonepad BOM and couldn't find any errors.

Is it "camping or drinking" or "camping and drinking" 

Might try that next time, instead of a tent just pack a bottle of Whisky and when night comes drink til you don't mind the lack of shelter. Might make the next days trail slightly shorter though 

[deadastronaut]

ha ha drinking mainly, any excuse to get away from the queens jubilee lark.. ...

[Perrow]

So that's why th Englishmen at work has Monday and Tuesday off they went home today and we'll see them again Thursday, Wednesday is a national holiday in Sweden.

About three more hours and then maybe I can get some time with my Small Clone.

[deadastronaut]

hmmm just tried a 4558 in this...(as per recommendation/tonepad/) at the bottom,  no sound at all...hmmmm...

358/072/ne5532 all had sound.......but not a sausage on the 4558 .a bit weird eh!..

[Perrow]

No sound at all from mine

[deadastronaut]

@#$%...

i just had the tonepad layout, and the new one side by side in photoshop, and i literally traced every part on both ..in pink..

and i can't see any problem...the only bit that was screwing my head up was the 2x56k's...but you just squidged it up..so god knows why its being such a @#$%er

try a different opamp...in the bottom.


i have lfo out of the 358..i connected an led to pin 7 of the 358 (even though mods say pin1 ) it and it flashes and reactes to turning up the speed etc...so thats ok..

[Perrow]

My lfo seems to work, but not the other opamp. And the 4047 gets only fractions of a volt on any pin. Wasn't in the mood for debugging today though

[deadastronaut]

mad eh!...yeah no more debugging till sunday/monday for me now....

shame i was really looking forward to hearing this!...oh well i'll get pissed all weekend instead!,,

[deadastronaut]

hi i'm new here , i know this is an old thread, any news on this?..

i'm back! had a great time, feel rougher than a badgers butt still, but hey thats pleasure n pain eh!...

right back to this mutha @#$%ing chorus!...any news pelle?



spotted a little error,  the 39k, going to the 180pf should be joined.....as in the original....i'll solder/jump it up and get back...

nope! still the same

@pelle: i have your diylc file now, i'll adjust those bits ok...

[Perrow]

If it's the one right under/close to the 3007, it's been mentioned before, but I've waited for more fixes before posting a new layout.

I won't be back until Wednesday evening, but feel free to find all problems before that.

Ps. Enjoy your royal headache
