hi quanghao

Thanks for putting this together. The boards look great! A simple suggestion for the boards. On the Dac-end boards the spacings for the supports of the heatsinks do not match the spacing for the support pins for the heatsinks that I bought from mouser. They are close but I have to pull out one of the pins to get everything to fit, which is kind of a pain. The pins seem to have a one inch spacing for both the aavid and wakefield heatsinks, and on your boards it is slightly less. Can you elongate the holes on these boards so that we can use the heatsinks from mouser?

Thanks

JimS

Welcome you!

I see great design Salas, So I need to PCB test before ordering, as well check everything I order, and I need the high quality PCB.

why a circuit design one layer so I make it two layers? because:

1. the circuit design is good ( I love it)

2. PCB design, I want layout it is good.

3. I need quality PCB,

4. My layout for two separate channels, you can use one HV shunt for pre, if current consumption is not too large.

So you should not worry about its price and time to complete the work.

Thank you all

Can you update the schematic to match the silkscreen, I'm having a hard time following the silk screen with the resistors numbered different, ie you have R9 connect to MJE350 on the SS but in between C4 & C5 on the schematic.

You are right JimS.
The spacing of 2 mounting holes for heat sink is not correct (off standard).
Most of heat sinks of this size have 1" (25.4mm) spacing. The board he made is 25mm. I think it was my mistake. QuangHao, you need to make correction on the next layout.
