A new TC7520 Passive/Gator Project
Hi,
I have a modified TC-7520, with Wolfson dac-chip, Oscon decoupling capacitors in digital area.
I am listening with passive output via two 15uF Obbligato Premium Capacitors. The Passive Output has two filters (low and high) according to WM8741 datasheet.
The 12V Power Supply feeding by Salas SSLV 1.1 and the digital 5V by a Murata Power Reg.
I have tried and the opposite, 12V by a LM317 circuit and 5V by a Salas SSLV 1.1
I love the sound of my dac with Salas Shunt Regulators.
The previous my new case project has small area for the two independent Salas Power Supplies.
For this reason, I am thinking now to change the case again, to something bigger for the two Salas Power Supplies. I am thinking also, to put a double output, Passive and Gator (changing by a switch).
Because I have not the circuit diagram, I would be grateful if someone could explain me what the exact Gator voltage requirements, and other non-digital circuit voltage (except the digital part of 5 volts for dac-chip & receiver that I know).
