Hey Brian, Toroids are the defacto standard for minimizing bulk and stray fields. There is problem with DC offset on the incoming mains but that can be easily...

So, here's my newest update. Still no ultimate success, but let me update the group and see if I can get a little farther. I spent a lot of time just doing a...
Had a bunch of guys over on Friday night for a transport shhot out between an Empirical Audio modded Sony 7700 and the new CD Pro2 transport kit (out of...
I recently picked up a Jolida JD100 cd player (with dampening added inside and on the feet + the EH tubes) to replace my ART DIO dac which I modified to...
I was hoping to see if anyone had any ideas on my next step. I will probably look at getting a chearp Oscope if I do not hear from anyone. Once this is...
Hey Bob, Thanks for the link. I'm in the market for a transport and it is good to know that there is something better than taking a Toshiba's digital out as...
Hi Mike ! I'm still here... Just being busy with my job ! I hadn't looked at the group for a week... I'll go through your posts next week-end. Cheers. ...
Peak, I haven't done anything to my DI/O for quite some time now. Never went to the class A biasing. Never upgraded the power supply beyond the suggested caps...
I have just joined.I would like to be able to post now thx __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has...
Hello I was wondering if anyone here has his modified dac?I am currently using it and was amazed by the sound.I purchased it to put on my surrond sound system...
I've been searching the archives and looking for photos that would help to no avail. If I go from the D/IO main board and eliminate the ribbon cable and i/o...
From the left, facing the main board from the back. This is just for D/A conversion, with 1- Digital signal 2- Not connected 3- Digital Ground 4- Right Ground ...
I think that I saw the part number for this listed on cfraser's site, but the link I have for that doesn't work. I melted the plastic strip that connects the...
I am not trying to be supercilious here, but why don't you read the circuit diagrams? If you try measuring component networks with a multimeter you may see a...
ART are notoriously difficult to get spare parts out of as per previous posts on `blown-up' digital boards. Why not buy a length of ribbon cable from your...
So I think it's time for me to move on. I'm ready to give up. Maybe I'll jump on the no-os bandwagon. I stopped messing with the dio for a while because it...
It seems a shame to junk the unit after so much work :-( If both chips are getting hot and burning out I would look at the common power supplies to start with....
I took your suggestion and looked at the schematic. It took me a while to figure out where the output was, it's on the far left side of the schematic (if you...
Brian- I'm not looking for a replacement ribbon cable, I was eliminating that from the signal path (repeated intermittent connections). I'm looking for a part...
Sorry Aaron, I understand where you are coming from now! You have two tried and tested choices. The first is the Digi-Key #WM3241 from Molex, but a simpler...
Glad to be able to help; it's what this group is for. Yes, the schematics are poor quality. I was hoping to be able to re- draw them but always found more...
Does anyone have a diagram of how to build the attenuators into a 1/4" plugs to drop the output to 2 volts? The link no longer works on the archived cfraser...

... The general feeling is that you're better off building the attenuators into the preamp end of the cable so you maintain a higher voltage level over the...
... Hmmm. I'm not sure I agree with the values of the resistors used here - they give a max. output voltage of 2.42V Vo = Vi x R2/(R1+R2) With: Vi = 7.75V...
