Default teac bx-300 amplifier

Hello,

I bought a nice old TEAC BX-300 (with MM and MC inputs). I search the schematic to upgrade it. If somebody have the schematic or informations to share, thank you in advance.

Thanks

Pascal

Hello,

I found the schematic.

In the preamp phono section there is a NJM4559.
An idea to replace it by a new generation opa ?
I have AD823, opa637, opa134, opa627, opa2134, ne5532, ne5534, opa604

Thanks

Pascal

J'ai trouvé dans un dépot vente un TEAC BX300 qui m'a attiré à cause de son entrée MC, rare pour un appareil de cette gamme. Il est OK. mais en l'ouvrant j'ai vu qu'il y avait une surchauffe (voir le jpeg). Auriez vous le schéma du côté alim pour être certain de la valeur des composants à remplacer ?
Cordialement

Cette surchauffe semble être classique sur cet appareil. C'est le troisième que je vois avec ce problème

Cordialement

Hello Sakis

do you know the word "Courtesy" ?

In any language BX300 service manual si BX300 service manual, if you are not able to clic on a link, sorry I can do nothing more for you.

A french site is in french, an english site in english, ..... perhaps if I have the time one day I will translate my site for english people, but actually I receive a lot of mails of english people (in english) who understand or who are enough intelligent to use "babel fish translator", or who contact me to have details about what they don't understand.

If you want to understand what is wrote on the Service Manual page, it's simple, I say that a lot of ******** have some service manuals and don't want to share them free. I pay my service manuals, but if someone need one, I share them free on this page.
It's like people who put some pictures of their amplifiers on the net without schematic. It's stupid, on Utube, ok, but on a site about DIY audio, it's idiot, the goal is not to see how much they amplifiers are nice, the goal is to share.

Regards

Pascal

Sonophile, this burned part of the PCB seems common on this amplifier. It's the 3rd I see like this

Cordially
