I see that in general that cheaper toroids are half the price of cheaper Rcores. As far as I can tell for the same or similar specification.

If someone projects Teflons and Mundorfs and Z-Foils, Tx type cost is small change though.

No wonder the economy is down the john.

Unable to find R-Cores ANYWHERE in the UK anyhow...

I saw "on the road" yesterday.
I have alsolutely no sympathy for any of the main characters in the film.
My comment to a friend as we left:
"if they have so little responsibility to civilisation as we know it, then they should all be put down"

If that film portrays the real attitudes and behaviours of our young adults, then no wonder the "world" is going down the tubes.
These irresponsible attitudes (I am all that matters) have led to where we are now !

Just for now...
...I'm having fun building a nice new preamp, "With a little help from my friends".
Cool advice from musical luvin' geezers.

Cheers.

Si.

The book wasn't THAT great; dunno how they could make it into a good film.
Try the paperback.

You mean there is a film based on Jack Kerouac´s book ?

Cool book BTW, I read it just before I read psycadelic baby reaches puberty from Peter Stafford

2nd tier quality solution is the 2x K170BL 8mA example I had posted. 2 junctions and more 1/F noise, but +2dB gain. Not bad at all in the end, still not the reference design exactly.
Thanks, Salas. Should have read the threads more- missed the 11mA IDSS recommendation.

Well, Jaap's 2sk369's are no go. He's got ~100, many patched pairs and quartets. But lowest IDSS is 14.9..

I have a couple of pairs at 11.4, 12 and higher.
So my boat isn't floating either.
