Finally, an affordable CD Transport: the Shigaclone story - Page 41

The PS board has been described here: http://www.diyaudio.com/forums/showt...72#post1237672 that is for full bridge.

If you are using two rectifiers only, just follow schematic and connect with main board section accordingly.

Mucho thanks

5 mins away from turn on now... this is where I get nervous!

Check PS before connecting to the transport.

Audio1st/Johnm. Have either of you (or maybe both) replaced the 16.93 crystal, if so where did you source them from. I would also be interested to know if you have done all the mods suggested by Okapi, and what have you replaced them with e.g black gates, Oscons, Panasonics ?

I have got mine up and running in my test system and will run it in before I attack it or put it in my main system.

Sorry Peter I'm having an evening of 'brain fog'!!! Would you mind taking a look at my pic of the PSU and indicating where I need to make the joins?

Think I'm getting confused as this transformer has no CT as it's the stock item that came with the JVC.

Thanks,

Hi Puffin.

I got my crystal from Peter, though I think Farnell UK stock it.

I will post pictures of my modified unit shortly - having to use camera on my mobile as I've lost the lead which connects digital camera to PC - grrrrr!

A few pics of my Shigaclone - next adventure will be the chassis

Puffin I used the following items:

Black Gate 1000uF / 50V standard (x 2) for the PSU board (board ordered from Peter). LM7808CT regulator, with two MUR860 diodes.

On the main circuit board I used the following:

C939 (E1) - 100uF / 63V Elna Silmic ARS

C953 (E2) - 330uF / 50V Panasonic FM

C929 (E3) - 4.7uF / 50V Black Gate N

C934 (E4) - 4.7uF / 50V Black Gate N

C916 (E5) - 47uF / 50V Black Gate N

C906 (E6) - 0.1uF 400V Auricap

Cheers,

- John

Another...

...and another - note the DPA DAC to the left. Once the parts arrive I shall be building a Shigaraki DAC clone.

Puffin, I am using a crystal from an old Yamaha CD player (Marantz & Phillips may be the same) with one board and left the other boards crystal as standard. I think John got his from Peter, or you can get one from DigiKey for £17.43, inc p&p.
I just used Panasonic FC's for the power supply and added some FC's on the board as well.
I think the transport just sound brilliant anyhow..
