Default Some guys may be able to understand portuguese

... Spanish language folks can understand...also some other latine people like Italians can understand.

Here you have test made by Newton:

Default Newton said it is all right.... he connected and adjusted

and this means it is all right.

He had to go out with the family to buy a house to weekend... a small farm to his family, reason why he will continue latter.

He said the amplifier is hot....of course he is talking about temperature because he have not listened yet.... only assembled and adjusted and found that temperature rise to 43 degrées celsius...yes..it is really hot.

In his home the temperature is 27 degrées celsius.... while he is out, a daugther will upload the video showing the adjustment...next will be listening tests.

Sorry..... of topic here....this is for the Dx Super A thread... sorry folks.,

Will copy and paste there.

regards,

Carlos

Hello! Hello! Today I tried to turn on the amplifier but I have continuity between VCC + and VCC-, that both channels. I do not know what's wrong!

I used traf 40V+40 V DC (400 VA) with 4X10.000mF/63V. Transistor are 2x2SC3263 + 2x2SA1294 + MJE15033G + MJE15032G + BD139

Thank you!

hello sir I'm not sure if you already fix the problem if you notice those 2 transistors need to be insulated and not touching the heat sink see image
the metal tap of the transistor is the collector the screw with watcher should not touch the metal part of the transistor I hope that is what it is a simple fix.

Is ok sir don't worried sometimes we forgot stuff I sometimes forgot wich one is the cathode on LED jejejejejeje it happens

the BD139 should be fine is already insulated

they are some brands of transistors that they come insulated or

also you can use plastic insulators too so the screw will not touch the metal tap of the transistor.
