Thanks My friend I will do this rite now.

good luck my friends. U can check component layout too on pic i give to meansure any error.

Any ting wrong here on my H900?

hey waylene, i check ur b900 again and i see many wrong here, please check ur ic NE, u put wrong position. Be aware any transistor on main headsink may have isolator. Check it. I see mje 340 biases tr on middle position miss isolator. Be carefull sir.

Hello my friend!!! Thanks for all your help! I appreciated much Highly. The mje 340 transistor is a covert with it's own plastic, with out metal side at the back. I will check the ic Ne now to see what I do wrong there. But still Thanks a lot my friend.

The MUR here that I mark with red here, is that the rite side I solder in pcb?

 

[jaagut]

MUR1620 is completely reversible.

 

[waylene]

What this that mean my friend?

 

[waylene]

Must it be like this here? Check Mur? Is that the rite way here my friend?

 

[jaagut]

What this that mean my friend?

it means you can install it without worry of mistake.

because the diode is twin. both legs 1 and 3 are the same. 😛😀😀

 

[waylene]

Hi there!

Amp play well, but only one side of transistors warm up. See where I mark with green, warm up, but there I mark with red, stay cold. Can you tell me what it can be.

Thanks.
