Is the 12AU7 tube soldered to the board, or is it a consumer-replaceable component?

The tube is in the socket. It is end-user removable in replaceable.

So basically this will add bluetooth input to an analog stereo receiver? Why would you need two aux outs?

  • This doesn't just "add Bluetooth input to an analog receiver". You can buy a cheap $15 Bluetooth receiver with an aux out for that. Generally speaking, a DAC takes full advantage of Hi-Fi (high bit-rate [24-bit or even 32-bit], wide-range frequency response) digital audio and converts it to an analog signal for receivers that don't have DAC built-in. I recommend reading up on DAC. These two articles put it in fairly simple terms:

  • I could see two aux outs being useful for any situation where someone needs to run the same audio out to two different inputs. For example:
  • 1 x Stereo Receiver and 1 x Headphone/monitor amp
or
  • 1 each to two separate powered speakers, etc.
