Almost done the mod on the SMPS
I put all the RUBYCON ZL capacitors
ALLThe diodes AND THE bridge diodes OF-
VISHAY SEMICONDUCTOR -VS-ETX0806FP-M3 -DIODE, HFAST RECT, 600V, 8A
Internal power cable NEOTECH 3003
Now remains only assemble two switching diodes
CREE - C3D04065A - DIODE, SCHOTTKY, 4A, 650V, TO-220
And finished
Some photo project

Thanks bro
I'm probably replace the regulators to the
teddy pardo super reg
TEDDY is from Israel i spoke to him a week ago and probably I'll buy the reg from him
Part II
Successful completion of the project
7 diodes were replaced to
VISHAY SEMICONDUCTOR -VS-ETX0806FP-M3 -DIODE, HFAST RECT, 600V, 8A, TO220FP
( 4 bridge diodes And 3 critical parts of the circuit)
In addition to two Schottky diodes switching
Replaced to
CREE - C3D04065A - DIODE, SCHOTTKY, 4A, 650V, TO-220
All capacitors in the power supply's capacitors replaced to
RUBYCON ZL Series
Internal power cable of the power supply was changed to
NEOTECH 3003

Now the device at BURN IN
From what I hear now
The bass feel with more energy
And background noise much lower
When I finished the 100 Hours BURN IN I could tell the general improvement

I finished the project on DENON DVD 3910
I changed in the audio circuit the Output Capacitors 100UF
To
VISHAY ROEDERSTEIN - MKT1813
10UF 250V
and the input capacitor audio circuit
470UF 16V
100UF 16V -3 CAPS
TO
RUBYCON - 35ZLH470MEFC10X16- 470UF
THE 3 CAP 100UF

Works perfect
Start the sound of the VISHAY ROEDERSTEIN - MKT1813 -10UF 250V
was harsh.
After a run of 50 hours
The sound has changed
I really like the color tone of the high frequencies
They are really accurate sound and Neutrals
It reminds me of the sound of my CD ARCAM CD192
In short very recommended capacitor
I'm going in the future in all my project to use them

I made another change to the audio circuit
i removed the 2 film capacitorsc 359.c357 parallel to the capacitors
MKT 1813 10UF 250V c361.c363
Remove on every route1 resistors 150 OHM R352.R355
( There are 2 150 ohm resistors in each route )
And bridged Where was then the resistors
With copper wire of NEOTECH 3001
Most importantly I took off the 4 mute transistors
TR303
TR304
TR305
TR306
The last two transistors that followed TR307.TR308
I did not remove
They function as a 0 digital mute
somebody knows what that means?
And is well worth it to remove them ?

I made other improvements to the power supply of the
DENON DVD 3910
Film capacitors in the power supply changed to
VISHAY 1837MKP
0.1UF
470PF
The resistors have been replaced by
VISHAY DALE METAL FILM RESISTOR
And most importantly
I increased the value of the filter capacitors of regulators
9 -
9 +
From 10UF
To 100UF
Of
RUBYCON ZLH 100UF 100V
Audio circuit
I replaced all the CF resistors
To
VISHAY DALE METAL FILM RESISTOR
And to all op amp
I added a film capacitors 0.1UF of VISHAY 1837MKP
From 4 leg to 8 leg
Voltage power lines that provide audio circuit i add ferrite filter
Of
WURTH ELEKTRONIK - 74272733 - FERRITE CORE, SPLIT, 8MM, 30MHZ
Frequency Min 150kHz
Frequency Max 30MHz

CAPACITOR TEST SHOT
Today I managed to assemble the electrolytic capacitor of
epcoc 100uf 400v
in the smps of the denon 3910
EPCOS - B43504A9107M - CAPACITOR, 100UF, 400V
EPCOS - B43504 Series
Capacitance 100µF
Capacitance Tolerance ± 20%
Voltage Rating 400V
Diameter 22mm
ESR 0.88ohm
Height 35mm
Lead Spacing 10mm
Life Time @ Temperature 3000 hours @
External Length / Height 35mm
Impedance 1090mohm
Operating Lifetime 2000h
Operating Temperature Range -40°C to +105°C
Ripple Current AC 0.64A
Ripple Current Temperature 105°C Tolerance
+ 20% Tolerance - 20% Voltage Rating V DC 400V
Instead of the
RUBYCON - 400CXW100MEFC14.5X40 - CAPACITOR, 100UF, 400V, 20%, 14.5X40MM
had to be creative to form a capacitor with a diameter of 22 mm
Area of 16 mm
1) Reshaped the legs of one of the bridge diodes Diodes FRED
2) And redesigned the legs of 200K resistor
After the burn in will judge the differences between them
