is the ca3094 obsolete?

[Sir H C]

I know several fabs that could do a run.  Thing is to find a high voltage process (now anything above 3.3 is concidered "high voltage").  Heck I have had to deal with the 1.8V "High voltage" devices.

Cost is the thing and tools though I have access to those.

[A.S.P.]

I`d gladly offer 20.000$ to a manufacturer
for making me 11.000pcs of a MN3011-remake.
I`d offer 1.000 of them to a well known DIY-supplier
@ 5$ each...

Okay, here is one we used to tell potential customers:

How many parts do you want?  Divide $250,000 by that number and that is your cost per part.  (for small quantity runs)

[A.S.P.]

above hypothetical calculation was merely replying the assumption in reply#5:

actually, I don`t expect a personal email-answer from a potential manufacturer
for a < 2million $ expected turnover quote-request...

Matsushita has stopped producing/supporting their entire line of BBDs.  So where do pedal-makers like these get them: http://www.visualsound.net/bbd.htm   They have them made.

Flanger Hoax from EH, read the end of first paragraph :

A few years ago, it appeared that analog delay based effects were headed for extinction, given that Panasonic no longer produces the necessary bucket-brigade delay (BBD) chips, but the appearance of inexpensive Chinese-made clones of the MN320X series chips made an innovative new BBD effect like the Flanger Hoax possible.

And back to OTA's, the old-school ones like, 3080, 3094, 13600/13700 may be discontinued, but maxim still has MLT04, quad multiplier that can be abused to get non-inverting OTA, or you can build a discrete OTA from few transistors.

There was some talk about discontinuing of CA3* line on synth-diy list, there was a guy who really tried to push the last maker to not to stop. But DIY'ers are smallguys, and big companies don't listen to them.

Speaking of the Ca3080, I managed to buy the last 15 in Australia from RS Components. They had removed the item from their lists just as I came in to buy some, and I got them for a great price as I remember. You don't normally score such good deals with old parts. 
Just enough to build that infernal microsynth.
