Looks good with a respectable high loop gain.

Hi, mostly interesting as the input stage for power amplifier designs, rgds, sreten.

Slow, should be more like 35V~140V/µS for the 140V rating for an audio amp.

Only 10mA drive.

$6 each.

Yes, I took a quick look and it is a bit slow for high power amp work.

You don't have to use it at 140V.

Who cares get some Darlingtons in there.

That's still not a lot of money.
