Mullard OC81D, and A Couple of New ICs

[smallbearelec]

I have a quantity of these that I will not be offering for distortions, because they are too leaky to bias properly. I thought of offering them cheap for use as diodes, so tested a few on the diode scale of my DVM. I expected a V fwd reading of 200-250 mv., and instead I see a consistent 130-140 mv. I thought that germanium junctions always hit the 200 mv. range. Is the lower V fwd good, bad, or indifferent?

In response to several requests, I found and have posted the BA3812L EQ-on-a-SIP, and the BA4560 SIP dual op-amp. I have a short list of other SIP types, and I'm fishing for those as well. They are all available, it seems. It's a matter of finding the company that actually has them on its shelves, because that's when the price is mosty favorable.

I really like the idea of the BA3812L, but I hate that it's surface mount. Am I wrong in assuming there's no longer an EQ chip made in full-size DIP?

SIP = Single-In-Line pack. 18 pins in a "staggered" dual array. Hard to work with on perf; maybe someone has done or will do a board layout for it.
