LSK174 I have never heard of.
LSJ74 we have all been waiting since 2006, or even earlier ??
The manufacturer has been saying that they are available soon, since then.

yes, the LSJ74 is not in production.

I tried their LS312 and 318 which is supposed to be their direct replacement for the LM394. It was more like a matched pair BC550. I actually got better performance from a matched pair of 2N4401s.

The nice thing about the LS312/8 is that they come in a 'can' but that is it. You are better off spending a few minutes matching 2N4401 or BC550C and get better noise results.

Yes! If you exchange the MAT, LM394 and 'real' equivalents in the same mic preamp and then put the LS318 in, the noise levels suddenly go right up.
Linear Systems technical will also tell you that the LS312/8 is not a direct replacement 'low noise' for the LM394 but will replace it in its footprint. I'm not sure what J Hardy is using in the JE990 now as the LM394 was discontinued a while back.

I learnt years ago that if you want clarification don't ask someone in a forum...ask the manufacturer.
