What about this capacitors
As replacing film capacitors 102. 682.471.

LCR COMPONENTS
FSCEX 6800PF 1%160V

LCR COMPONENTS

As replacing film capacitors 102. 682.471

I cant find that one,where is it?

 

[dazzz]

I think replaces all film capacitors
This company

LCR COMPONENTS - FSCEX 1%

Example

FSCEX 1000PF 1% 250V - LCR COMPONENTS - CAPACITOR, FILM, 250V | Farnell Israel
470pf-clr components fscex-1%
1000pf-clr components fscex 1%
1200pf-clr components fscex 1%
6.8nf-clr components fscex 1%
10nf-clr components fscex 1%

I also buy at the end 14 electrolyte capacitors of
NICHICON - UKZ1H101MHM1 -100uf 50v

 

[Ryssen]

Yes,that maybe wise to do.

 

[dazzz]

The only film capacitors thet i not found
18nf-100v

 

[Ryssen]

Where is that located in the schema?

 

[dazzz]

C395,396 -(183jt)

 

[Ryssen]

Ok,maybe you can paralell 2 smaller ones or series 2 bigger.

 

[dazzz]

Meanwhile I leave the capacitors of the original 18NF
I hope that after I replace 40 parts
The sound will be worth the effort
A week and a half until the parts arrive
i bought All equipment for the project

 

[dazzz]

Finally I ordered all the parts for the project

I finally got all the components I ordered Electronics
Project to upgrade the audio circuit 3910
Meanwhile I put 40 parts of the 60 i order

I finally finished the project improved audio circuit

[Ryssen]

Have you tried it yet?

 

[dazzz]

Now he goes BURN IN
100 hours
But for starters I can tell
The sound has become much more accurate
High frequencies Snmaim much clearer

And the sound stage is much greater
Remember we talked so what OP AMP responsible stereo?
i learn from Mistake of installing OP AMP
STERIO OP AMP are C301.C302.C.303.304.C305.306




At first I changed as you recommendations the OP AMP C307-C310
I did not hear a difference
So I started to replace the OP AMPS C301-C306
When I hooked it did not sound testing
On the left
I checked what the problem OP AMP C305
Was not installed good

I fixed it
And now everything works perfect
ׂ( Before you say
The device is set
SOURCE DIRECT-ON in the menu )

So two stereo channels autput op-amp is C301-C306 100%
Learn from mistakes lol





It was a lot of work
I changed about 60 parts
10 OP AMP
14 resistors
and most
Film Capacitors
Electrolyte capacitors

 

[Ryssen]

Good to hear that it`s working and that you hear an improvement.
Are you going to mod the PSU next?

 

[dazzz]

mor photo of may denon dvd 3910 mod

 

[dazzz]

yas
stage a audio circuit mod- Mission completed
stege b- i will do the psu mod-next
stage c- master clock

 

[dazzz]

Now after I finished the MOD
I can now enjoy the Music
my stereo system - YouTube

 

[dazzz]

Good to hear that it`s working and that you hear an improvement.
Are you going to mod the PSU next?

I now begin the design of the PSU
I will use the Monfrad capacitors
Now
what a diode company you recommend for the diode bridge ?


Another question
I want to replace the MASTER CLOCK
You can bring me a recommendation for one

And a link to who sells the specific model that fits DENON DVD 3910 ?

 

[dazzz]

Hi
I am now beginning to plan for the mod of the PSU
Of 3910
I start at the bridge diodes
This model of the diode that is now in the DENON -EM01AT (V1)

I think I will use those what you think

FAIRCHILD SEMICONDUCTOR
RHRP8120

8 A, 1200 V, Hyperfast Diode
????

DIODE,FAST,8A,1200V,2-TO220AC
