[miguelnoda]

hello I have a question that has prior background noise is normal or has some kind
of problem could be the relay or the gain, as my previous one has nothing
is empty at low volume.
thanks

 

[miguelnoda]

hello also like to know if you can solve the heating of PCB 3.3K resistors
thanks

 

[mikojat]

Hi Miguel,
Background noise at low volume can come from anywhere, such as your amplifier, source and from your preamp to. Did you check your amp without preamp?

Resistor's with 3k3 rated in 3 watt (R101,R102,R301,R302) serve as the loads for the transistors, it is normal if they little heat.😀...

 

[miguelnoda]

Noise is a blow and the amp only and does not heat up enough resistance the output and input have made ​​very little
damaged the circuit board.

Hola Miguel,

El Aleph L no tiene ningún soplido (Tampoco ninguno de los de Pass HUM que tengo tiene ruido), es muy raro que el tuyo si está en buenas condiciones lo tenga, estaría bien revisarlo (Si por privado me dices donde estás te puedo recomendar a alguien).

Hi Miguel,

The Aleph L hasn't any noise (like all of my DIY Pass preamps), if the unit is in good condition, it is very strange that your unit does emit a noise. It would be a good idea to revise the preamp.

Regards

Has anyone got the schematic for the Aleph 2X

 

[KatieandDad]

As Ramallo says. My B1 is completely SILENT - completely BLACK in operation.

It's now running with a regulated supply but it was SILENT with just a standard rectifier capacitor supply.

If you send me a Private mail telling me where you are (located) perhaps I can recommend someone (to help you out).

pass labas

Hello someone would have pictures of the inside of this amp x2 to verify
if one of the diodes of the source has a bridge, as in the lower part has
a resistor and a diode soldier on the surface of the PCB.
-Miguel

 

[miguelnoda]

Hi I would also like if someone has the workshop schedule. I here found the source, I need the audio circuit.
Miguel, thanks

pass labas x2

I have it if you want to say to you in private
(miguelnoda@telefonica.net)

 

[miguelnoda]

Thank you and I have the scheme, all are very friendly.
Anyone know if you can get the new PCB.
Since mine is a deterioration in the resistance of 3.3K-3w.

 

[miguelnoda]

For Nelson Pass
I wonder if you could get the X2-1 PBC as resistors 3.3k3W PBC Burned me know if it's not a problem or is so
for hours of use, if not would have got way to update it.
Thanks, Miguel

 

[miguelnoda]

Anyone know if you can replace the PBC on the x2-1, if someone sells or is cloned, mine is bad for the 3.3K resistors burned him enough.
a greeting

 

[generg]

Hi Miguel !

I do not think you will have a chance to get a new or a clone board.

Why do you not solder with some wire new connections for the two 3k6!

But be aware that the IRF 610 also could be damaged, look at the service manual for the sourounding components and check all voltages according the service manual.

🙂 only chance maybe to ask Mr. Pass directly, look for his email on the First Watt page.

I'm sorry to tell you that we no longer have that board in stock. Fabricating
a one-off would cost too much, so I suggest that you simply confirm that the
existing board still has a connection, and if not, make one.

😎

 

[miguelnoda]

There are possibilities to do so and much will it cost is that I like before, if you want photos of the state control board, or if you could make the version.
a million thank Nelson Pass

Problem with amp

Hi Miguel, mr. Pass and others.

I offered Miguel to help him with his amp (via PM).

Miguel I know (more or less) what the problem is with your amp.
I want to help you with this amp and am willing to do this for free !
So if you come to Holland or send the pre to me, I'll fix it for you and send it back to you.
The pictures of your PCB shows that your PCB is not damage in such a way that it can not be fixed. I've done this before and I'm willing to help you.
Let me know if you are interested and want to accept my offer and consider it done!

Send me a Private mail or post your reply on the forum, both are OK with me.
Porfavor remite por e-mail privado o via el forum te ayudare gratis!

Atentamente,
Sincerely,

José
