Nope. There are a few, with the 990 mod just one of them.

Before we started to digress a lot a helpful participant listed post numbers.

But now I can appreciate their gyrations as having been pedagogically motivated.
Right. They were mathematicians that designed some discrete opamp, drunk some wine, then started dancing.

The JE990 with a FET front end is SOTA?
#2060 is stone age but with SOTA performance

Damir, cut us some slack. I'm in this to learn from the true gurus but I also want an invite to the drunken orgy .. I mean wine tasting they are organising next year.

Then I gotta hitch hike across the Pacific with a dead kangaroo as my contribution to the eats

Everyone's well behaved and cheerful... a little bit of off topic isn't too bad, as long as it keeps the cogs on turning and no one loses an eye. It's a good thread, let's keep it that way. The mods are here, watching, as always, no worries.

This is a kind of discrimination, if someone other went of the track you would cat it immediately. I am concern only that useful staff is burred under ...

Ummm . . . . perhaps the OT discussion dragged on longer than it should have, but considering all the useful contributions the participants have made, I'm willing to be a little lenient.

While yall were imbibing I've been tempted to post the schematic of this (on page 2) and ask if there could possibly be anything wrong with using it for audio. It says right on the data sheet "Wide Bandwidth."

Be careful what you ask for, the most knowledgeable posters may end up starting up a DIY winemaking forum and abandoning this crazy audio-and-electronics thing!

A friend who worked for Compaq considered the discovery that the 324, output-loaded to run class A, could be made to sound marginally acceptable for audio to be highly proprietary I would add that the standards for acceptable were not too terribly high.
