Default Phono/Regulator PCB

Hi Quanghao and others,
Yes I have received the PCBs as I said, and am in the process of building them, but other work keeps getting in the way and the need to earn money is very high at present.
I am initially just going to build the phono stage as I already have a PSU that will be suitable. My idea is to put it in a diecast Hammond box at first to sort out any assembly/wiring/component problems and then get a custom enclosure made by a friend as I will need to add some moving coil step up txs probably Sowter 8055s. Hopefully will take some pictures and put them up here.

Regards

John

Working great!

I was scared about the transformer and everything being so close together in one enclosure but luckily no hums or other noises.

Hello all,

I am starting to build mine. Yes I know it is almost a year after the PCBs have been made, but you know not enough time, small kids and all

I see there are some errors on the board that have been found, and also that there are two versions of RIAA corrections. Quandhao, would you be so kind to post the last schematic for RIAA and regulator please, so that I am sure on what I am to build. Also would you post in the same place where to take care on errors of the PCB.

Thank you in advance,
Pred
