Hi Daniel,3. I prefer 3 secondaries. 2 >=15Vac for the analog / muses circuit and 1 ~8Vac for the control and relay circuit.
will this Toroidal Transformer 30VA 2x15V + 1x9V also be ok?
Yes, the output buffer is recommendedWich output impedance has MUSES72320? Do I need an output buffer for connect it to a headphone amplifier with input impedance 2 KOhm and less or a power amplifier with Rin=6.8K?
a plain buffer with opa1656 is just fine. I use it myselfYes, the output buffer is recommended
Hi @meldano
I'm interested also in main board, control and volume attenuator. But before that I'm building a tube amp which already has pre-amp embedded.
Would those boards allow me to handle remotely: volume control, on-off, source selector and does this set comes with loudness filter or some version of that?
Regards,
Lucas

@meldano thanks for the quick response. Looking for a remote solution, which takes advantage of MUSES72320 and perhaps this kit is almost a perfect fit for 3 of my tube amps. Would it be possible to take advantage of STM32G031K8T not connected outputs to control separate boards e.g. one that handles on-off? or it doesn't make sense due to high power consumption on amp standby and I need a totally separate circuit with separate ir receiver?
I have developed a web interface for my big preamplifier.
The web interface runs on a Raspberry Pi Zero.
The Pi is electrically isolated from the preamplifier controller.
The web interface operates bidirectionally, meaning the status updates on the web interface even when adjustments are made directly on the preamplifier using a rotary encoder or IR remote control.
Here's a sneak peek.
Is there interest in using this as a controller update for the Muses from the thread?
