This ain't no charity. I need the space, but you need the part more. Yep, them whiz-band converters do take up space.

Default 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.

Talking 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.

Default DVD mods??

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]

Talking 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}.

Default 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.

Ren

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.

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.

Jocko

Isn't it the case here in this common gate arragement ? Drain current variations are converted to voltage ones using the 1K5 drain resistors...

Did you made comparison between Mosfets/BJTs, varying bias current ?
