Low-noise preamplifier/powered DAC MJE15034 TL072 based on STUDER 900

[Vasilii]

Good health to all! My name is Vasily. I bought this board on Ali veriya 1.1 resistor 112 on it is marked on 75 ohm instead of 15 ohm as on other boards is this a typo or features of the version of this board? And another question instead of mje15034 what transistor can be put the board is needed to power the DAC. Thank you in advance for your answers..

Hello Vasilii and welcome - I can't help with your question, but I guess others will chime in.
If noone reacts you might also consider asking moderators to move the post into another, more appropriate section (you can just use the report button and ask there).
