floating around in excess for quite a while. I managed to pick up 100 of ebay for
10 bucks not so long ago, and I was the only bidder (they were old RCA ones
though). But yeah, there isn’t really a lot too them, so making an
equivalent circuit using transistors is not really that difficult. The single
package does make things a lot easier and compact.</span></font></p>

to make Intersil keep the 3080 in production? Soon there will be no OTA
produced in the entire world! And what will we do then? After the CA3080 is
canceled, only LM13700 will remain, but god knows for how long. There is no
practical way of doing inexpensive analog stuff without OTA’s.</span></font></p>
