Hi ichicban,
thank you, but is Google translations from German to English is a chaos.

I found a interesting article on the web.
I try also to download the pictures

@ Indianer,
in einem Punkt kann ich dir widerspruchslos zustimmen…..

>> Und das SCHÖNSTE ist, es kommen immer neue Erfindungen, äh Verkaufsagumente hinzu. Mit jeder neuen Erfindung gibt es gewaltige Verbesserungen der Klangqualität, und das seit 2006. Irgendwann müssen die Geräte doch explodieren vor lauter Klangverbesserungen. <<

…… aber da hasste das „r“ bei Verkaufsargumente vergessen.

Zur Vergegenwärtigung der Positionen siehe Bilder. (Bild 1 und 2 sind rein symbolisch zur Darstellung der Messpunkte da unter den Lesern sicherlich auch Laien sind. (die Opamps wurden von uns absichtlich abgedeckt)

Gemessen am ausgangsseitigem Opamp eines SCPH-1000 Board's mit EVO II (*) Überarbeitung einer 3,1 Kg schweren Cochise – 1000 Virginia der ersten Baureihe, ALLE Ansteuerwiderstände der Ausgangsstufe entsprechen Erst/Originalbestückungssollwerten (**).
Wohlgemerkt erst nach dem EVO II-Programm benennen wir die PlayStation hochmodifiziert.
(*) EVO II ist ein von TET auf reinen Audiobetrieb modifiziertes PS1 Mainboard, ALLE für den Audiobetrieb unrelevanten Sektionen wurden abgeschaltet und im Anschluss entfernt.
(**) SMD-Ansteuerwiderstände müssen auf rechts/links Pegelspreizung geprüft werden. Eventuell müssen sie gegen auf Gleichheit selektierte ausgetauscht werden, da bei 18 k auch bei den üblichen 1 % Toleranzen +/- ist 2 x 180 Ohm zwischen den Kanälen theoretisch bis 360 Ohm Unterschied die bei einem einzigen rechts/links-Widerstandspaar auftreten könnte, tatsächlich liegen die Werte sogar oft über der Toleranz. Bei den 11er Boards sind es ein 10 k Paar und drei 18 k Paare, die für die Ansteuerung beider Kanäle ausschlaggebend sind. Der Folgefehler der auf der Strecke bis zum Ausgang bei zu großer rechts/links-Spreizung dann bei einer zusätzlichen Leistungssteigerung entsteht wäre ohne Korrektur hörbar.

Bild 1 Unterseite Mainboard Ausgangsstufe Dual-Opamp

1 = OUT A = 2497 mV ~ bei 1000 Hz 0 dB
2 = - IN A = rechtes Signal
3 = + IN A = + 3670 mV –-
4 = V – = GND

5 = V+ 7300 mV --
6 = - IN B = linkes Signal
7 = OUT B = 2497 mV ~ bei 1000 Hz 0dB

8 = + IN B = + 3670 mV --

Bild 2 Oberseite Mainboard DAC und Ausgangstufe

L = Ausgang Wandler linker Kanal (1463 mV ~) 1380 mV ~ bei 1000 Hz 0 dB
R = Ausgang Wandler rechter Kanal (1463 mV ~) 1380 mV ~ bei 1000 Hz 0 dB

Wir bei TET-Computerspezials denken schon dass dies doch eine Steigerung bedeutet es handelt sich hier immerhin um ganze 374 mV ~ wohlgemerkt ALLEIN am Wandler bzw. an der empfindlichsten Stelle des Signals, und deshalb wären es eigentlich 1463 mV ~ aber wie es halt an dieser empfindlichen Stelle nun mal ist fällt die Spannung beim ansetzen der Messnadel um 83 mV ~ ab, siehe Messprotokoll. Aber streiten wir wegen der 83 mV ~ nicht rum, uns genügt wenn wir wissen das bei uns am Wandler schon fast so viel anliegt wie bei Indio an den Cinchbuchsen. Den Rest besorgen die, wie war das noch? Die „Impedanzwandler“ und wenn wir wollen wäre da nach oben sogar noch Potential. Und wir sprechen hier erstmal über EVO II, dabei ist EVO III durch und kann nach dem Stresstest in ein paar Wochen ihren einjährigen Testlauf/Endspurt bei unseren Testern im Bundesgebiet antreten. Mehr möchten wir zu EVO III bis zur Übergabe eines Endgerätes an ? aus verständlichen Gründen noch nicht erwähnen.

Bild 3 Messung der Ausgangsleistung Ausgangsstufe bei 1000 Hz 0 dB

Bild 4 Messung der Ausgangsfrequenz 1000 Hz

Bild 5 Messung der Ausgangsleistung am DAC bei 1000 Hz 0 dB

Bild 6 Messung der Netzspannung Abgleichsdarstellung

Bild 7 Messung der Netzfrequenz Abgleichsdarstellung

PS. Falls Interesse besteht eine ähnliche Aufführung der Messdaten vom Testaufbau einer Zwischenversion EVO II zu Stufe III, einfach melden. Dieses Gerät wurde probehalber mit zwei BB2134UA umgerüstet und hat eine Ausgangsleistung von 2670 mV ~ bei 1000 Hz 0 dB, bzw. oder hängen wir doch Bild 8 noch mit an.

Sollten Zweifel bestehen, bitte rechtzeitig voranmelden und vorbei kommen, dazu bitte gültigen Ausweis mitbringen da wir das Ganze dokumentieren werden.
Eure eigene PlayStation gerne modifiziert zu vergleichen ist selbstverständlich auch willkommen.
Ausdrücklich erwünscht ist, dass das eigene Multimeter mitgebracht wird, und eine Frequenz-CD 1000 Hz 0 dB, wir möchten nicht dass im Anschluss behauptet wird unsere Messinstrumente wären präpariert.
Diese Einladung gilt natürlich nicht für den $-Indianer und zwei weitere Stammesmitglieder Grünwald und Schlüter.
In diesem Sinne Grüße nach Ascheberg.

Leistungsplus 61 - Tet-Computerspezials

First I would like to introduce myself.
I'm Edi Helmle since 2006, the development director and chief of the company TET-Computerspezials.

I spend a very long time and in detail with the audio features and the possible modifications of the PS1, actually from the beginning since the first edition of the Japanese NTSC / J issue in December 1994.

Due to our tremendous growth on the PS1, and with the final stage reached in the 5th Generation Evolution V with 4.9 V ~ eff. I decided. I will give the most important for the course of history the TET-Computerspezials at PS1 audio modification for international use freely.

"This modification increases the output voltage of PS1 by 61% from 1.06 V ~ eff. to 1.7 VAC rms.

This modification can be applied to ALL PS1 motherboards with TWO OpAmp's in the output stage.

Our "Leistungsplus 61" is compatible with many other modifications.
"Leistungsplus 61" affects with significant increase of the audio quality.
"Leistungsplus 61" has no negative effects on the rest of its electronics.
"Leistungsplus 61" can be done by anyone even by laymen.
"Leistungsplus 61" it does not cost a cent.
"Leistungsplus 61" does not require a component
"Leistungsplus 61" can always be undone.
In "Leistungsplus" You only need to remove a resistor from the motherboard."


The easiest, cheapest, most efficient and most important modification for PlayStation1
was developed 17 years ago.
Everything else you see in the picture.
An externally hosted image should be here but it was not working when we last tested it.

Attention! only at the PlayStation1 with two OpAmp’s in the output stage.
The English version of the publication is available on request.
Expressly desirable feedback
in this sense, a lot of fun with the "Leistungsplus 61" TET-Computerspezials

I couldn't find it through thread search, so I'll just ask. First time poster, long time lurker on this thread. I've actually enjoyed my SCPH-1001 stock for a while now, but am planning to bypass the caps in RCA and AVout. On dogbreath.de it says 100uf caps were used with success, but didn't specify a rated voltage. Anyone have any opinion on this? I'm not really planning on making a new output stage.
 
Playstation modified

Hi masud,
it is a very good modification, it took me only 5 minutes cost, and it sounds wonderful. This application on the PS1 can really the DIY make self.
I thank you for pointing, and also the developers at TET-Computerspezials.
I think Mr. Manfred is not more competitive in the low-price segment on Ebay-Germany.

@Masud

For all of us is the PS1 modding just a hobby we have fun with. We must also not be taught by voodoo priests.
Everyone makes their own experiences and share them with fellows. We must not compare our results with a COMMERCIAL PROVIDER who pursues other objectives.

Manfred´s web page is just for handicraft´s, nothing else.

:Pinoc:

Pg2005,
I thought it is not commercial

Hey buddy,

I think u haven´t read anything I wrote. If Mr. Manfred sell´s his modified
ps1 for some pocket money, than it is up to him.

But you forgot that he offers his knowledge for FREE in his "howto" on his web page.

By the way did you see his new tutorial how to fix an Playstation 1 Laser Lense drive

AND EVERYTHING FOR FREE

I dont even understand your stupid comments about that manfred want´s money for his clever and professional FREE hint´s.


for everybody comprehensible and it only cost´s a couple of cent´s.

I really think someone is talking out of his bottom.

I am waiting for your comments and why are you going on at me instead
to see that some person is filing this thread with sevveral accounts.

please explane mr edi´s picture - but had

the price of $ 10,819.84 is in no relation to a modification that does not cost 50 USD for spare parts.

An externally hosted image should be here but it was not working when we last tested it.

Is the price fair? Not really. But I haven't really seen the problem with selling modded goods that are relatively simple (for a lot of us on here) to do. Its one of those incidents where if people are either inexperienced or lazy, they will get charged a service premium. In this case, a crazy high premium lol

Dear Pg2005,
this is a company with a professional rail for high technology. 400 % more output voltage 4,9 VAC rms on the Playstation is a sensation. It is a option for rich people. But she also have a rail for DIY, and for 0 cents.
I think it is okay!
Everyone can benefit from it, also you.
The prices in the low segment will fall dramatically, and the prices for the consoles with two op amps dramatically rise, now anyone can do for 0 cents. Afterwards the little man will not more on Ebay buy a modified PS1 for 300Dollars, and that's good.
Is that your problem?
But that's life.
We should discuss further at this level!
Leistungsplus 61 - Tet-Computerspezials
And not about dirty laundry!
We should more respect have for the engineer, who give for the little man after years of stagnation this chance.
It cost not a penny, and my PS1 sing so beautifully

Pg2005, I want to ignore you from now on!

and the rest of the world, good modified

I'll give my humble opinion.

First I'll start by talking about Mr. Nelson Pass F5, with a simplicity of components has a sound that hits many amplifiers 4 digits.

That said, I have also burned some eyelashes and made many experiments in PS1002.

This is to say that those who follow the simplicity of Mick Feuerbacher get the best possible sound, I'm sure of it.

The DAC is the brain of the beauty of these pieces, why put more parts in the signal path? The signal quality is very good, we can increase the output but will affect the signal, is unnecessary because it serves perfectly for any amplifier.

DIY is giving and sharing knowledge, PS can sell it, but terrestrial price, $ 10,000 is anything that does not fit on the head of anyone, because these boards have several years for various reasons and there are components that are due to old age malfunctioned as fuses, smd, etc ...

So the output replacement is the best method? I adore your enclosures by the way, I'm taking major inspiration from your wood front one for my build :D

simplicity is remove one smd-resistor

Yes Blink_PT,

Good morning all together,
from Ellwangen/Germany, we have now Monday 24 September 2012, it is 1.00 clock in the morning.

For all, you can my version of the "Leistungsplus 61"

>> visit the link <<

http://tet-computerspezials.de/6.html

combine with the version of Mick Feuerbacher.
There is no problem,
It's just a little more work.
Also more output voltage,
with better soundquality

Please note!
It's only with motherboard with two opamps from the Series SCPH-1000, SCPH-1001 and SCPH-1002 possible.
And now, good fun all together.

To clarify issues.
The 5th Generation "Evolution V"can you not buy, we produce 4 different types only 15 units per year. They are for a selected clientele.
Ebay is just advertising for us.
