Awesome work super 🙏👌👌 I'm impressed 😇💖👍👍

[@andreazis]

So good! I have a Sony dx 50 with damage in STK, and now i know to repair it.

[@ezequielrodriguez3085]

Me parece genial cambiar solo la etapa de salida de audio exelente trabajo 👍

[@OscarSonyProfessional]

Realmente solamente es lo que se hace amigo se sustituye la etapa de amplificación y listo

[@Patata0ke]

Hello. Do you guys know a link for STK490-110 datasheet? I Don't find any IC to replace that is why I'm looking for a datasheet so that I can follow its input and use another amp just like this on the video.

[@Patata0ke]

I have an Aiwa HiFi component though

[@sammac8042]

Can we change amp board same like this

[@NelsonBeltranSalas]

Bien el cambio, pero el trabajo de soldadura ordinario

[@Justyoutubing479]

[@DDDiego1000]

Buenas Me interesa la plaqueta (amplificador) donde la compraste ?

[@hectorcabrera794]

Esta muy bueno el video me encantaria hacer el curso de electronica jajaja

[@ucukbie123]

Boss if the stk got mute... Should we.. or uss to cut down the mute first... Coz some of sony gn88 got muted problem..

[@bsnc1708]

Buenas Esto se le podrá hacer a un Sony GNX80, q es un equipo de 5: dos frontales, dos surround, y un subwoofer? Es decir que le quede llegando la correspondiente señal a cada una de las cajas. Gracias

[@joffrecarlosolveracadena339]

Ese modulo es d 2 canales stereo podrías alimentar los 2 frontales en un canal en paralelo en otro canal el subwofer

[@omsairam9728]

Super 👌👌 👌

[@j.jeyamurugannadar6031]

Very nice 👍

[@MarcosLopez-jw3hx]

Buen trabajo.pero yo en lo personal no cambiaria el modulo con el stk.para mi son muy buenos y con una calidad de sonido y potencia muy bueno

[@EstebanSS]

Ya no hay STK originales, solo copias y salen muy malas

[@mohdkhairi3271]

Do it this,watt original STK shall diminished?

[@reyuchannel7232]

I think it's better if the original block got repaired

[@nileshjagtap2652]

[@jasper14een]

how did you connect heat sync to body ?

[@patrickadilexx8062]

Sir how do you convert that transistor amp from stereo to mono

[@electronicchannel1797]

The circuit is even so much, I have so many simples and strong circuit.

[@СултанШарипов-р6ж]

Не плоха. Класс. Гап ек, мани калламга келмапди.

[@christojoseph2476]

Why did the STK burn ?

[@jayantanandi6990]

[@topgearIQ]

Who is the best stk or transistor

[@DANISHAhmed-eq2yb]

vhai konta best STK na tranjistor

[@joffrecarlosolveracadena339]

me parece que se va a esforzar mucho el transformador con esa etapa de amplificación

[@irvintan167]

Thank you for the information

[@Amirsabha-o5r]

This receiver especially has a great powerful sound Its a great job but i votes for factory sound

[@edwin2963]

Good effort but its better and cheaper to repair original sony amp as its has better sound quality

[@sureshkoduri815]

Which ic is given good sound quality.

[@Patata0ke]

probably the same sound as the IC because that amp does not have eQ. all the eQ adjustments is still on the sony dsp.

[@earlmaycatalan7383]

Can you try to convert a sony MHC-RV6 into transistor amplifier? Im just needed help😉, thank you😊

[@tecnologiaexperimentosyvid3758]

Está bien el cambio pero por el estado del equipo de audio me preguntaría si vale la pe a hacer ese cambio o usar la etapa que está adaptando por separado, además no soy experto pero algo que mejoraría antes que nada es quitar el polvo y óxido además de mejorar la punta del cautín y mejorar su técnica de soldadura que la verdad deja poco que desear, de antemano no lo tomen como crítica destructiva sino como algo constructivo, te felicito por el vídeo y por el ingenio, lo único que ahy que ver es si el voltaje y amperaje son los adecuados para evitar distorsiones así como la ventilación ya que conozco bien la etapa de audio que está reemplazando y genera baste más calor lo que degraria los componentes

[@toto073081]

What amplifier ic module you used?

[@tareqrana6551]

Bai sound kamon hoi??

[@rohitchaudhary3469]

Sir sony mhc rv5 me kon sa Transistor board lgega

[@bijuvs46]

The smoothness of the sound wont be the same as before and there will be distortion also.

[@arthurhilario5388]

Where is the sound Sir ,stop playing nonsense music ,we want to hear the good sound if OK or not,,

[@Wilfonalt76]

Buenas noches amigo. Te escribo desde Barranquilla-Colombia. Me llamo Wilfrido y quisiera realizarle ese mismo trabajo a un equipo de sonido que tengo y que no quisiera reemplazarlo, sino hacer un trabajo como ese. Me gustaría saber, qué referencia tiene esa etapa de ampliación que le pusiste a ese Sony. Qué precio tiene? Y si hay alguna genérica en caso de no encontrar esa acá en mi país. Gracias de antemano y espero su respuesta.

[@treadmillrepair754]

En ebay puedes encontrar amplificadores digitales muy baratos y fáciles de instalar. Los buscas con el driver IRS2092s. Saludos.

[@pramodmohanty6192]

How is the sound quality? Can it match STK quality sound? You should have play the music...

[@salvadordiazmercado9970]

Me gusta las adaptación les a ser equipos sony a todos los modelos puede instalar placas amplificador solo algunos equipos sony preguntó

[@hareshpatel3411]

from where can i buy this circuit board ?

[@jordanch68]

Is this module available anywhere? Thanks!

[@danielm.4359]

Huge disadvantage of these sony hifis that there is no standby transformer so the main transformer always ON. And the 5200&1943 amp desaign that you used don't have a standby circuit so it will always work even if the unit in standby mode.

[@samkp6941]

Exactly

[@PY5IH]

You can adapt an CMOS IC CA4001 or CA4011 performing an mono-stable circuit with an Relay feeding the main transformer. All linked with the power main on/off original key. Google it.
