I'm glad you liked it. I hope everyone, especially HPotter, noticed the TDA1541A "Crown DAC" sitting on the board mounted in anti-static foam. (Someone buy it. The DAC, not the player.)

CD80
Hi there,
I have a CD80 that I really rate, could you give details of what you have done, I'm at the start of a DAC project, with TDA1541 S1 with CS8412 I want to try zero OS and some nice I/V stages.

HPotter:
Did you also notice that motorized volume control.
Why don't you drive down to Texas this summer, and help me clean out my junk box. Bring cash. [joke]
Mozfet:
It is not non o/s!!!!!!!! There is no TDA1541A S1!!!!!!!!
It uses the board that I made recently, you can see a picture of it in the "For Sale" area.

No TDA1541?
How CAN it be any good without the sacred TDA1541A (S1 of course) and all those extra samples (we dont know what they were wanted for). Actually I have not tried a Non OS Dac yet thats what I'm doing at the moment.

Jocko:
Your board looks really good. Too bad it cannot be used in balanced setup (or at least that was my impression). But to modify players it's perfect. Also the chips you are using, when implemented correctly sound terrific. Good idea is to use quality, separate VCXO.
Do you also have board to remotely control Alps pot. That might be of interest to quite a few people.

Harry:
You can use it balanced with 2 mods.
1.) Run either the LData or RData into both DACs.
2.) Invert the phase pin on one of them.
Then you need 2 boards.
I use balanced for my setup, but none of the people I do work for have balanced. And it was designed to "fix up" players. I have other designs for stand alone D/As. But they do not sound as good as an "all-in-one" unit. Even when I design it.........
The pot came with the CD-80. I had to move it a bit to make it all fit. I think I have a few left from people who didn't need a volume control.
Mozfet:
Stop using those things! Or buy my surplus ones.

TDA1541AS1 price?
Hi Joko Homo,
whats the deal? If I pay the shipping you can use the storage space for some of those nice Whiz Bang Convertors you like, de-evolution indeed! Are we not Men?

De-evolve yourself!

This ain't no charity. I need the space, but you need the part more. Yep, them whiz-band converters do take up space.
As "Mad Dog" Miller likes to say: "Don't even forget to bring the cash."

Cool player
I'm with you Jocko man. It is better that I should have to wear unwashed lederhosen every single day for the rest of my life than to listen to one of those stinky TDA1541. 😀
Tell us some of your DVD player mods too.

TDA1541
Hi Ren,
<i>Lederhosen</i>, <b>stinky</b> TDA1541.....?
The TDA1541AS1 is not that bad!. I missed the bass slamm and sparkle of the AD1865 but the TDA1541 surely does not sound "digital" or harsh.😀

Are you nuts? What am I going to do with one of those SMT parts farms? Shove one of my "whiz-bang converters" in there. I don't think so. Jocko don't play that.
Stinky, eh? Unwashed lederhosen, yep, that is stinky.
Harry:
Hear any "digital" or harsh sound in my player? Any lack of bass?
(dramatic pause........no response.......)
No........I didn't think so. All done sans '1541. (And you Europeans thought I don't know any foreign languages.) [joke]

DAC
Hi Hpotter,
Wow, A case full of goodies!
What are these greenish thingies in the row from front to back?
Jocko, Any change on a schematic for the discrete IV stage? Can <B>you</B> wash that stinky <I>lederhosen</I>?[joke]
I don't wear clogs, am I?{never did}.🙂

DVDs are cool
Get with the new century, jocko man. You can do all kinds of cool things to them. As long as it looks or sounds different you can charge money for it.😀
Audiophiles are cheap, man.😀
Stop working on old stuff, man.😀
Be cool.

Elso:
Those green things are capacitors in parallel with electrolytics which are under the board. Also there are 6 transformers on the left, they are stacked on ea. other.

I can't even get him to give me one and I have one of his DACS with the damn thing in it! GOOD LUCK!

OK guys first clue...........
Look at Nelson's I/V. It is probably the same type of thingie. Just put a BJT where he uses a MOSFET.
MOSFETs are transconductance devices. Current in, voltage out. It works, but I prefer BJTs. Transresistance types: current in, current out.
Then convert the current to a voltage with........a resistor. Just like some guys do without having to build an amplifier after it. Paul McGowan.......you still aren't paying attention, are you. Thought so.
As for "Ren".......I'll deal with you later.
