BBD RETICON SAD1024 under voltage controls Subject description: PAïA PHLANGER ? |

Hi,
Does anyone know if it's possible to add CV inputs to an old electro harmonix Electric Mistress Deluxe flanger ?
I've done this already - replacing onboard trimmers by pots (Thomas Henry) :

Did anyone try this, the PAIA "PHLANGER" :

SAD 1024 flanger under control voltage, +/-9V... Last edited by funkyfarm on Sun Feb 25, 2007 3:33 pm; edited 1 time in total |

Of course, this may have been covered over at Aron's Stompbox forum, but I would look for the junction of a 33k resistorand 1uf capacitor which feeds into the VCO built around the LM311. Break the connection with pin 2 of the 311. Connect the 33k/1uf junction to one side of a 47k pot, connect the other side to the voltage control input and the wiper to pin 2 of the 311. You should then be able to dial in the internal and external CV in whatever proportions you want. You would have to find out what voltage range the external CV needs to be. |

Thank you, so maybe Aron's the better place for this...
So i would transform the topic into :
did anyone have a VC-SAD1024 module in his set ? like the PAïA PHLANGER ?

hmm...
Looks cool, but it doesn't work...
As stated in the manual, I've substituted the single 2N5129 for one 2N3904.
but I've also swapped 2N5139 for 2N3906...and THIS IS NOT STATED IN THE MANUAL...
2n3906.pdf
2n5139.pdf
There is no clock at 4013 outputs...one is held to Vdd, the other is stuck to 0v.
Controls seems to be OK as I turn potentiometers.
Will give a try with another LM3900 soon.
I tranlated SPEED to RATE
SPAN as DEPTH...
I guess CENTER looks like a DEPTH CV...
I've found this strange "CANCEL" input to be the wet signal bypass, implemented in rather strange way too
Do you know what to put in ? Last edited by funkyfarm on Fri May 11, 2007 2:35 pm; edited 3 times in total |

Thank you !
As time goes by, and as no one seems to have built this "PHLANGER", I guess it should be real shit.
hmm, waiting for another 3900 IC... |

I used to have an A/DA flanger - like Mosc's Electronotes, mine got loaned out and that was the last I saw of it
That thing spoiled the hell out of me - it was my first flanger, and I just assumed all flangers sounded like that. In my total ignorance, I loaned it out and didn't pursue it when it didn't show back up (what the hell, a flanger's a flanger I stoopitly thought). There's only one word for the situation - Dammit!!!!!
I've got an actual Thomas Henry VC Delay that originally had a SAD4096 in it, which was toast. Put in a SAD1024 and it creates some wonderful flanging/chorus effects (you probably remember that episode, Stephen, the case of the nasty breadboard). I remember back in the MAP days, Thomas had the project posted for public access. Hmmm......... |

Yes I do indeed. I have the Thomas Henry VC Delay article somewhere and a board, but never thought of replacing it with a 1024. Definitely one for this summer! Does anyone require ADA Flanger Circuits? |

I think I've once heard this before, but it was too late.
I guess you've once send Mike Irvin's ADA FLANGER modified for SAD1024
BTW I didn't understand what was the original IC, but

No, I want TWO !
And tell me SAD4096 is more or less four SAD1024 in one chip, and I can collapse on-line |

The SAD4096 is more or less four SAD1024s in one chip.
Well, it's the equivalent of four SAD1024s. I've heard the SAD4096 probably wasn't the most robust of ICs.......
The MN3010 was sort of the Panasonic answer to the SAD1024 (and took over for the SAD1024 in later models of the A/DA flanger), but they're more rare than the SAD1024, which itself is approaching the level of golden hens teeth. SAD4096, on the other hand, is one of the purest forms of unobtainium that exist today. If you look up the word "unobtainable" in a dictionary, chances are there will be an illustration of a SAD4096 beside it.
Cheers,
Scott |

Do you mean one of the PCB's that Moosapotomus had done? If so then yes! Not sure how I missed out on those.

I could maybe do another run of those if there's enough interest around here.

Tell me if another run is done please!
Any idea of the shortest possible delay with it?
I mean forcing it to the <1ms range

I'd venture to say really, really, really, really short. There's nothing quite like the SAD1024 (unfortunately).
Moose, forgot to mention, nice to see you here in these parts!
Cheers,

Thanks, Scott. I have no idea why it took me so long to discover this place. It's chock full of wicked cool people and "stuff".
For those interested, I think another run of the ADA Flanger Clone boards may be in the very near future. I might start another thread here, to avoid hijacking this thread, and to see if there's enough interest to make it happen. Stay tuned...
Thanks
