Hi guy,
I've been searching for alternative jfets, in case the 2SK170 becomes scarce--and for the shear fun of trying something new--and because I'm a tightwad on a budget. Ok, the last item should have probably been first in line.
I tried simming with a replacement from the SIMetrix library: 2N5484 was the first in line, so I gave it a go. I had to reduce the current, but it seems to sim nicely.
Anyone ever try this approach?

I've been scouring over my folder of "Choky" stuff. I reexamined the pumpkin (got to build that someday) and noticed he's using the J309.
That, of course, gave me the proper search word for DIY Audio. Within seconds, I had a long list of posts to read. It seems the J309 and it's J310 sibling are making more than one owner happy.
Off to Mouser I went. They have the J310 going for the ridiculous price of $37.00 for 500 pcs. I'm going to give it a go. I can match transistors and build amps until the moon falls from the sky at that rate.

Also by me.

I bet in 5 years you would have no choice (especially with digital), so you better start practicing. There are enough hints on the forum, e.g. by John Westlake.
> You really ought to start a DIY web site.
Until I retire, or you volunteer to do it for me ?

I'm too busy working on my own site to expand. But, if I had the time, I certainly would help.
Weebly.com is free and easy enough to use. Just think, you can post a blog (they offer one for free) and tell the world all sorts of amazing things.
Your archive is already stored here. So, either way, I suppose we're safe and sound.
I'll get going on that surface mount stuff. Assuming I'm still here in 5 years...

not true Patrick--I always like to see what you have to say!
Carpenter-
For what its worth, I have built with J105's and other Vishay jfets. The circuits have always sounded very good. Perhaps not quite as good as a Toshiba part, but they are still orders of magnitude better than most of the hifi components I own. (especially preamps.)
