since the old 2sk389 is not available at reasonable prices (a few NOS's around) I have been pointed to the lsk389 which is available locally (at least in my state - TX) and I notice the same supplier also has the new Linear Integrated Systems lsk489 which is rated at slightly higher noise but much lower gate to drain capacitance. Any comments or experience.
choose depending on what you need for your circuit.
they are different parts.
look at the tranconductance difference; high gain comes at a price.

going to use them in the first stage of the Gilmore SS ELS amp.
their press release didn't talk about gain so I did not pay much attention.
the data sheets were obviously written by different people - Vds vs Vdg etc. and I am not really confident in my ability to draw conclusions
