Hello Quang Hao,

I think it would be a good idea give the people the posted/tracking number of the letters, I dont know how the post system works in other countries,
here in Brazil I can see exactly the ariving and way of your letters in Brazil, but only after receiving the letter when I saw the number on it.
Sometimes have a delay in the customs or goes a wrong way, when you can see it post tracking system you have time to speak with the post.

Hello!
After I finished 4 phono, my favorite is the sound of it, so Andrea has recalculated the values in the circuit. I was very interested in these calculations. Motherboard I do for you called a phono ASH.

Today, I use 50 ohm resistors cadoc for cathode tube D3A , and 0.68 UF capacitor output Jensen. Sounds great.
I had a chance to compare with the EAR 834 phono
Phono D3A (ASH) te sound is better 834,
and I like D3A phono in the following points:

The sound, balanced, very high resolution, Nature
No noise,
Probably due to light interference is very small electronic D3A
SO it is very good Phono.

All i still need before the power supply test is my 120k 2W resistor.
I also need better screws for the heat sinks and i need to put in isolating washers so that the heat sinks are not live.

After the power supply is tested i will connect it to the phono part and test. YAY!!

I decided to mount my large capacitors underneath so when i design my enclosure i can easily make my tubes protrude at the top for a classic look. On too Autocad!!

Hi Tang,

It goes looking fine, Im also was thinking to make a cabriolet version and perhaps separate the power part in another chassis.
But Im just looking around for buying the parts, where do you bought yours, in a thread you told for making a list?

Here is my Bill of materials so far.
I bought all the "funny" parts from rs components. The rest of the "standard" parts you can find very easily at any electronics shop.

Some parts have the RS part number that I used next to it.

I have added notes with the errors i have found so far.

PLEASE NOTE:

I used the original RIAA circuit with 33nF and 100nF I DID NOT USE THE EXPENSIVE silver mica riaa circuit. You will have to change the RIAA resistors and capacitors too your needs.

I have not tested my setup. Only finished soldering last night. I will test within this week.

Good luck

Tang
