ssl9k mat02

readin, reading and searching, searching...now can anyone please tell me: 1. can i get mat02:s anywhere, if yes; where? 2. is there any replacement (mat12, lm394, etc) that anyone used and can confirm that they work properly and sound good?

I used LM394 on one of my builds, no probs, good sound.

get them from analog  devices:

I dont think you can get < 100 but you can order samples... works for me

Hi,

if you go to AD web site and do a search for MAT02 you'll get a response that says:

"OBSOLETE PRODUCT — MAT02:  Low Noise, Matched Dual Monolithic Transistor.
This part is not recommended for new design. Please see the MAT12."

and MAT12 is available at digikey for incredibly low price starting at 29.60$ a piece

This would be my second choice.

Regards, Renx.

Are these knock offs?

everything out of chine is a knockoff, seriously.

So what's the biggest downside of that, especially with these? Would the matching be suspect?

I would suspect matching, well, not match... Or it could be just fine, but if they're branding it to be something that it's not, it will likely be a let-down, but you never know until you get one.

As ytrertef says the LM394 if you can find them are fine as well. I have an ssl9k with
a lm394 and a ssl9k with a mat02 and I can't tell them apart.

AD MAT02EH
I offer these , email me. Also, there genuine AD semiconductor die.
tested.

Until now I cannot figure how they charge nearly $30 for these.
It way too high a price. Were talking about two simple transistors
on one die. In fact , the only difference I can see between these
and two single transistors ( matched ) is that the MAT02
are thermally coupled ideally on one piece of silicon. You could probably
take two single TO-92 pkg. transistors and adhere them together for thermal
coupling effect like on some versions of the 2520 op amps and run them.
But I have not tried this yet. Also the thermal coupling in this case would not
be as effective since two transistors on a single die is tremendously more efficient
method. temperature does have a marked effect on matching and performance.
