TDA1022 NOS (high quantity)

Postby tube_S_cream » 20 Nov 2015, 16:40

Hello there,
a friend of mine got a large amount of the Philips TDA1022 Bucket Brigade Delays, which were used by several companies fo analogue Chorus, flangers or Leslie simulations (Dynacord CLS122, Korg CX/Bx Organs, Wersi-Voice, Boehm Phasing Rotors und many others).
Some of the best sounding Leslie sims where built with that chip.
We've got over 700 of them, bought after a sale of goods bancrupty estate of a german electronic organ manufacturer some years ago.
Currently they seem to be a real treasure....
All Chips are NOS in sealed trays. If anyone is interested, send my a PM .

This thread might be worth a reply. Or, I pressed the thanks button over a week ago but some real response is suitable as well.

The TDA1022 seems to be the only (non-mn23xx) BBD that never went into "unobtainable" status. A real treasure... hmm, not really... but at these quantities they're attractive for serious projects. Nothing commercial though.. they're non-ROHS

My suggestion is to contact the current IP holder for the Jurgen Haible designs and push him to work on reissuing the TDA1022 based tripe chorus sooner than seems to be the planning now.
Sorry. Plain out of planes.

Must be a typo error.
A tripe chorus doesn't sound so appealing to me but a triple one really does.

I hope it will make the Michael Landau sound possible.

Thanks for the salt :mrgreen: yes, I meant triple indeed.

In that perspective it's rather curious that the 3-delayline based chorus can be found among various key applications (Korg poly-something, Siel Cruise, and quite some Eminent-Solina quickly cross my mind) but vey little in a guitar or standalone form. Therefore making that Dyno-My-Piano suddenly very interesting dus to a lack of competitors.
Sorry. Plain out of planes.

Now let´s see:
The JH Triple Chorus is ment to be a clone ("Emulator") of the Eminent Solina Strings Ensemble:
http://www.dragonflyalley.com/jurgenHai ... horus.html

The Eminent design by Van Der Kooijt was filed for a patent already in 1973:
http://www.freepatentsonline.com/3833752.html
In any case the patent has now expired.

And yes, unfortunately Jürgen passed away on 26 November 2011:
http://electro-music.com/forum/viewtopi ... 494#346494

The change from TCA350 to TDA1022 already has been made by Solina themself in their rev. 8. The maximum "IP" Jürgen could have left is the pcb-layout. Therefore I doubt that there is a legit "IP-holder to contact for reissuing" the Solina Strings Ensemble clone. But at least the JH pcb-layout can be seen here in all its beauty:
http://www.dragonflyalley.com/construct ... Chorus.htm
Now..... who wanted to have a pcb ?

Hi.. just one week out of office and a lot of posts here :-)

If there a questions relating to price, shipping etc. you can contact my friend Erik .
His adress : info@boehm-orgeln.de

Maybe that he has still some schematics of the old "Phasing Rotor 78" by Boehm which ist quite similar to the "Wersi Voice" .

The old Boehm-Company closed in the 90ies.
The new small company is a kind of "custom shop electronik organ manufacturer" , far away from the DIY-Kits in earlier times.
All their new products are completely DSP based.

The Flanger Hoax doesn´t use TDA1022....

But here is YOUR chance to demonstrate what you are able to do :wink: :
