Ahh....I noticed something interesting in Doepfer's new product
offerings...look familiar to anyone?

http://www.doepfer.de/a1831.htm

Not unlike a late-70s era Moog 995 triple attenuator, a Doepfer A129/3
Attenuator/Offset, an Analogue Solutions ATT-4 quad attenuator, or a Blacet
2210 Multi/Attenuator, I'd say.

No, no, no...

They're completely different: in one, the knob is above both jacks,  
and in the other the knob is between the jacks. :-)

Re:  Chuck Graef's comment..

Functionally, you're absolutely correct.  But sticking it in 4 HP with
the same functionality (less one important feature I don't want to
mention else that may cloned as well) puts it into another category.

The point I'm making is we all 'borrow' technology.  Hell, a very
large portion of the 21st century offering are lifted directly from
old circuits.  There are five main subcategories in play here:

1) Intentional and direct duplications (Stiener Filters, the Polivoks,
the Wasps and Bananalogue offerings to name a few)

2) Circuits found in Electronotes (we all do this, that's what Electronotes is all about)

3) Circuits from manufacturer's app notes - this holds particularily
true with anything that incoporates vactrols. The Perkin-Elmer note
has about every application you'll ever need for a vactrol right
there, public domain, inviting you to use them and ther opto's with it.

4) Modules taken from PCBA-level products (Ken Stone's and Ray Wilson's products have been 'modulized' by a number of companies)

5) Because it's the only practical way to do a certain function (for
instance, the VCA on the M25 - 3080 based with nothing unique on how it was incorporated and probably done by others, ditto for the M38).

All this happens, and will continue to happen.  It's all good.  But
what's going on with the A-183-1 is a bit different.  I would hope
words 'inspired by' will be found somewhere in it's technical
description!

it's almost like dieter's elves have been hard at work.  :D

Happy New Year everyone!  We made it, survived 2008!  On to a better
brighter 2009!

May you all have many new fortunes.
