Quanghao, I have the ES9018 ver 2 dac, how do I use the onboard 3.3v instead of the USB supply. Is there a jumper to set? or remove? on the DAC board? Can you please provide some information? I am going to use the I2S input, but I have to activate the 3.3v supply, please help.

Thank you Quanghao, ok, so $45.00 for the tube output pc board, $35.00 for the power supply and $25.00 for the shipping, so $105.00 total?

Can you also add the 3 heatsinks for the power supply and the 4 output capacitor for the tube output, please? if so, how much are they?

Thanks Quanhao, you do fantastic work,

Thanks Quanghao, I already have a lot of parts on hand, but I am just looking at the pictures, would you mind sending me the schematic and parts list so I would know what I have already? I already have tubes, sockets, diodes, etc. But I only want, what you already have, dont order them for me, just the ones you have. If you do not have the output capacitors on hand, then thats ok, I will order them myself. Maybe, I need those power connectors you use, I like those, male and female.

For the tube I/V, I see small relays and balanced outputs and some IC's, for me, all I need is the balanced input and single ended output. I will have to bypass the relays and controls, am I correct?

So I think I will only need the output caps, heatsinks, and connectors and the boards of course.

Thanks,
Alex Deveza
