CA3046 replacemnt ?

[mbartkow at ET.PUT.Poznan.PL]

Opps, it seems that there is no point for looking for a replacement,
if they are so cheap.

Anyway, the UL1111 is a local product and there are heaps of them
on the Polish market. I managed to recycle a data sheet from ages
ago and compared the basic parameters as well as the pinout (thanks
Quint !) which are identical. The substrate is also at pin 13, and 
there is even a modest claim about the compatibility with CA3046.

Thanks guys.

BTW, what is that whole hype about uA726 ? It is very easy to form 
a temperature stabilised oven using two trannys from the 3046 and
an external opamp. I have built such circuit, and even saw few
similar working very well in particular applications. We have three
transistors left perfect for an exp converter.
