Hi,

what is the vantage to put a transformer between DAC and I/V?

With my little knowledge I think it would be better put a transformer after the tube to illiminate the C2, how Andrea have made in his DAC-End.

Hi Quang Hao,

with the new PCB for SSHV for I/V Pre you have changed the circuit, you are using now the same of the the D3a phono pre.
Iīm also interested in the E182CC version with output transformer, why you donīt make a two PCB version, SSHV and I/V seperated.
I just have 2 of the D3a SSHV PCB.
You have chematics for the new I/V-SSHV for DAC?

Klaus

Hi klaju1955

Do not separate between SSHV and I / and E182CC wit transformer output, I will send you the following diagram.
You're signing on to the list! Thanks for the interest.

Hey guys, about to order 1uf caps. I'm going to order 2 x 1uf Mundorf Mcap Supreme for the I/V. Was just wondering if I need premium caps for the Salas Shunt as well.

Also, in the BOM, it says 2A/800V Diode 1N5819. Is it suppose to be 1N5062's instead cause the 1N5819 is 1A/40V.

Thanks
