SOLD
This my extra set of Miro AD1862 DAC board, fully populated and functional.
You need to have a set of psu to supply +/-12V and +/-5V to the DAC board and also an i2s source of your choice for it to play.
Resistors on the board are high quality, low noise ones from TAMA electric, Nikkohm. The IV resistor is DALE Blue version, which is of military grade offering high precision, tolerance and non-magnetic.
Bypass caps for the logic ICs are Kemet SMD MLCC x7r types.
Bypass caps for the digital and analog stages are Kemet MKP.
Electrolytics bypass are Nichicon FW series and Panasonic FC series for the DAC chips and for the IV op amp section are Nichicon KZ.
Op amp for IV stage in this sale is the dual op amp LME49860, mounted on the dual to single adaptor.
Fact:
1. The AD1862 chips are bought used for my testing. I have been running it for at least 2 weeks or more without a glitch. They work as they should and sound no less than the new ones from my purchase from the Rochester group buy.
2. The positive 12V input pin pad under the board has been partially lifted. However, it will have no problem soldering your pins or cable on the remaining part of the pad, and the pad on the top layer also provide full connection.
For 125USD, coffee for Miro, who has been very helpful and generous, as well as shipping with tracking included.
