I run Tina Ti on Windows, so I do not know about Mac, but apparently somebody use it on Mac with an emulator. See link below if it can help:

studer 900
I have used these supplies and been guided by the Sigma 11 thread in regard to voltage drop. Around 7V seems to work . I did enlarge the heatsinks.
I haven't used more than 1A through the supplies and quoted max has been 2A.

Nuts, you guys, you bought all the Studer 900 PS Supplys.
I wonder when they'll have more to sell.
Cheers,

Is this a tongue-in-cheek remark 🙂..?... or you really cannot find cloned Studer PSUs online...? The original Studer 900 PSU is not manufactured anymore, the only source being the (very) occasional second-hand one...
No, not tounge in cheek. They really are sold out. I went back to look... The are now closed. For Chinese New Year. 🙂
Hello,
I'm using one of this in my raspberry+katana, 5v 3amp both. It works fine. I bought this:
Kit de placa de alimentacion de amplificador STUDER900 con disipacion de calor en Amplificador de Electronica en AliExpress.com | Alibaba Group
This kit can supply 5v 3A without changes. First tried 12v ac and it gets too hot, can´t touch heatsink. Then I changed to 6v ac and works perfect.
I had some problem setting voltage, maybe this helps others:
VOLTAGE RANGE: there is 3 solder bridges marked as H M L (High-Medium-Low). Left open the voltage you need, and close other 2 with a solder blob. Then turn pot, very easy to adjust to 0.01v.

I'm surprised that it can work with as little as 6V ac. The Studer circuit (see pdf linked to in this thread) shows 10V across the TL072. Perhaps the actual output of your transformer is more than 6V?
I am really confused about this board.
Same pictures...same board on audiophonics,ebay,aliexpress...but different info abut max current...from 1A to 2A.
I can see some people say it can do 3A.
😕

You can't trust the specs. because they don't state the voltage at which the stated current is available. The ebay merchants are mostly re-sellers who don't know much about the board at all.
With an appropriate AC input you should be able to get 1.5A at 5V. If you want a continuous 1.5A you would probably need bigger heatsinks.
I'm successfully using a 5V boxed version to supply my RPi 3B+ (slightly underclocked and under-voltage). I had to fit a lower current-limiting resistor to get enough current. The MJE15034 transistor is heatsinked to the case, which gets only slightly warm.

Thank you jonners.
You helped me many times.
I've read in this tread what you did and I am glad you have solve the problem.
Cheers

Victor, If you use this board as a main PSU for the Katana kit supplying 12AC to it it is no suprise that the small heatsing cannot cope with the dissipation of a large amount of heat created... 12VAC x 1.41 = 16.92VCC after rectification and smoothing... meaning a drop of 12VCC to regulatory 5VCC. If you multiply 12VCC with the value of the current required for the task you'd get a self-explaining figure measured in 'watts'. A bigger heatsink or a quiet fan would help a lot in such cases. Are you sure that you've supplied 6VAC during the 'successful' trial...? It's a bit too low to work properly, I believe, maybe it was 9VAC...

Hi Jonners
You are right. Transformer label says 6+6 volts, but I measured it and actually is 7.0V ac under load. Output 5.0V dc and 6mV ac (standard multimeter). Heatsink is just warm, I can keep my finger on it.
Do you think 7.0V ac is too low for regulator? Can I expect improvement going to 12V ac again? If I do, I should change heatsink.
Thanks
Victor
You explain it perfecty. I didn't my homework and had to fix it later 🙂
If it's supplying a fairly steady 5V when the RPi boots up it's probably OK. I think 12V ac would be too much.
Hi all,
I need to build a power supply 12V-2A for my Terratec DMX6Fire, this board can match with my wish but the specs is not clear ...
How much ampere the board can output with 12V out ?

I think it can provide 2A. But check power dissipation.
CallMeMike explains it very well in a previous post.

I recently purchased this Sturder KIT, I soldiered it and have few issues.
1. Toroidal transformer have 6V AC output (after connecting Sturder psu have 7.3V DC at the output)
2. Led are not glowing
3. It cannot regulate voltage (tinny screw)
4. By soldiering L/M/H contracts nothing change, it gives voltage at the output also when not soldiered
