Extremely high beta is generally a characteristic of low noise transistors (and low Rbb). It is not necessary for long tail pairs but won't hurt.ungifted said:

ps: caveat I did not look at SSL9k so speaking in general.

A company in Latvia is listing a part that looks like LM394:
http://www.alfarzpp.lv/eng/sc/AS394CH.php
"The AS394 is a junction matched monolithic NPN transistor pair with an order of magnitude improvement in matching over conventional transistor pair. " --- word-for-word from the LM394 sheet.
They also list the CEM synth-chips.
Distribution seems slim.

.. ;D
..But actually, not only are they alive, they also reply quickly!
Short answer:
Yes, AS394CH available. MOQ (minimum order) = 100pcs

I ordered a mere 5 of the AS394 to try them out and they arrived to Los Angeles in a little over a week.

What did you use them for and how did they perform?
I'll be using them as an input differential pair like the 990. I'll update as soon as I do.
I bought MAT02EH from this source in the past, and they were real and I can only recommend it.
I don't remember if there's a minimum order or not, I ordered 10 at that time
MAT02EH
The price is $6.0/pcs . We'll directly ship them from Shenzhen .

The good folks at EricaSynth sell the Latvian Dip and TO5 for 2.7 and 3 Euro respectively in one off quantities.

Cyrus, did you ever get around to using these AS194/AS394s? What we’re your conclusions if so?
