denon dvd-3910 service manual ?

[michaelsamra]

I only changed to the LM4562 in a couple of PC soundcard and the sound came out clearer.
I changed all the regulators in the PSU (DVD3910),but I´m not sure about the outcome..(soundwise).

Truthfully,there are so many good dacs out there at reasonable prices that it becomes ludicrous at times to mod the audio path when you can just come off the transport into a DAC...I will try it tho.

 

[Ryssen]

Because I use the digital output.

 

[dazzz]

you now thet when you use digital output dsd is convert to pcm

 

[michaelsamra]

Thank you very much for the help bro
I appreciate it
I'll put lm 4562
Another question if you can
You also recommended switching capacitor in the circuit ?
and what brend ?

In the switching capacitors,I would use Nichicon muses..They are perfect and priced reasonable. Truthfully,the logic switching circuit is not going to degrade or improve your audio...That all is done the audio path itself.

I know.

 

[dazzz]

I think to order the workstation


Hot Air Combined With Soldering Rework Station BAKON- SBK8586

Does anyone have experience with them ?

 

[michaelsamra]

Because I use the digital output.

I use the digital output also .

I ordered the OP AMP LM4562
There is something a recommendation on the types of capacitors and whether to change their values ​​because of a change of PO AMP 4562
From 2068D?

 

[Ryssen]

That "cap" is maid up of 5 singled caps you would have to use this formula to calculate the new value f=1/(6,28xRxC) (where R is 30k) of a single cap.

I did not understand
What do you mean
Capacitors 1 worth 5
Can you give me new values ​​of the capacitors if I replace

 

[dazzz]

There is something that made the MOD
on the dvd denon 3910
after change the op amp from 2068d to lm4562
And can give me the variable changes he made after replacing the OP AMP
Companies capacitors ?
What must change and what can'll stay ?
Help is welcome

If you use a "plastic" cap with the value of 4.7uF you get the -3db point of 11hz.
It all depends on how much you are willing to pay for 2 caps.
I have got no experience of plasic caps,so If sommeone who has are willing to advise.

I ordered 10 OP AMP 4562
I plan to replace all the audio circuit OP AMP
I hope that I will have problems after that

You mean two capacitors in AUTPUT STAG Large capacitors electrolyte
?

 

[dazzz]

Can I replace the electrolyte capacitors 100uf-50v in the audio unit circuit
weth
NICHICON muse-kz series 100uf 50v

They are not expensive and I've heard they are good
What do you think ????

And it says 1000 hours
It seems a little odd
Capacitors for quality

 

[Ryssen]

Yes its the 2 brown elyts,and yes you can use muse-kz,but I would wrather use sommething like this maybe 10uF Mundorf Film Caps EVO - Aluminum + Oil

100uf is cost 80 $
160$ for 2 cop Expensive

Why did you write 10UF ?
Now that the device capacitors
c 363
c 361
CE04W1H101MT(ASF)
100uf ?

 

[Ryssen]

Well you can use 100uF e-lyts if you like.

 

[dazzz]

Well you can use 100uF e-lyts if you like.

this the capacitor I think I will buy

NICHICON - UKZ1H101MHM1TO - CAPACITOR ALUM ELEC; 100UF; 50V; 20%; RADIAL
CAPACITOR ALUM ELEC, 100UF, 50V, 20%, RADIAL

LCR COMPONENTS
FSCEX 6800PF 1%160V

LCR COMPONENTS
FSCEX 1000PF 1% 250V


LCR COMPONENTS - FSCEX 470PF 1% 630V - CAPACITOR, 470PF, 630V

 

[Ryssen]

Why did you write 10UF ?

Because the 100Uf is oversised,you relay don´t need more than 10uF to get an -3db under 10Hz.
And Mundorf Film Caps EVO - Aluminum + Oil
is of a better quality than an e-lyt,but a little more expensive.

But its up to you.
You decide.
