Anyone know anything about this device? Out of an old SAE amp, but I can't find info on this thing...

Hi EchoWars,
When I can't find the original number, I use the selector guide to figure out a sub. You know what the minimum voltage breakdown should be. The gain in modern devices will be in the same range as the original, given production tolerances. The current and power are normally dictated by the package.
So look up current TO-66 packages in On Semi. You can use the TO-220 package as well. It's a driver, so a few amperes was likely the original rating on a 100V+ device.
Now the money question. What was the model of the amp?

SAE 2500....

2N6213, could use 2N6421

A little hard to find.

Plastic no good here, no SOA.

Also used in Levinson ML3 as predriver.

I think I have some of them new in my workbench (I bought them on 80s and built an amp with some pieces)

I will see and I can send them for you if you were interested.

And there are also TO66s in the Jap 2S series as used as drivers in Sansui amps and elsewhere. Don't recall the numbers offhand.
