Group Buy for: The Journey of DIY No-Feedback Class D Amplifier (1)Subtitle: The Motivation and Story Behind It

To power the amplifier, I prefer to use two 48V switching power modules with PFC, each capable of a maximum output of 350W. Any comments?

The result of using 92 high-precision thin-film resistors is a 23-step stepped attenuator. Both left and right channels have balanced inputs, with a matching 5K ohm input impedance.

Hi everyone,

The amp modules are now ready to ship! As mentioned before, the price is $350 USD per unit. I can accept the following payment methods:
  1. Zelle (maybe it is for who in USA only)
  2. PayPal
  3. Bank transfer
Due to recent changes in import tax policies, I had to pay an extra 45% in duties. So, if you're using PayPal, please send the payment as a personal transaction (friends & family) — otherwise, PayPal will charge an additional ~5%.

I’ll ship out the modules in the order I receive payments. To thank you all for your support, I’ll cover the shipping costs myself.

Before sending payment, please email me first so we can confirm the details — that way, I’ll know who the payment is from. Since this is my first time doing a group buy like this, I want to be extra careful to avoid any mistakes or confusion.

Thanks again!
