leave them as is

gate stopper and protection zenner for excessive Ugs

 

[miguelnoda]

thanks so and will not let tensions finds when replacing components that have asked, I have no clear is the diode bridge
zener.

Hola Miguel,

Just leave it like ZM said they look original to me.
The only thing I would have done differently is put a (isolating) sleeve over the leads of the components but nevertheless it'll still work if you don't touch them.

I urge you to test the whole amp by using the schematic you send me and if everything is OK than you need to go deeper in to troubleshooting cause by replacing the (damaged) parts alone and not getting the amp to sound good you will be needing a helping hand from a friend who can fix it for you.

Again, it's not difficult to do this and with proper explanation you'll be able to fix it.

Now a question in Spain for you: Tienes el ruido o soplo en anbos vocinas o solamente en uno de los dos?

Do you hear the noise in both speakers or just one?

Gracias, Thanks,

Audiofanatic

anyone know of few Kohm potentiometer is Pass Labs X2-1
and if you can put something better as a DACT.

[Nelson Pass]

The Elma switch is the best I know of.

This pot have the same quality as DACT, don't touch it.

 

[generg]

Even DAC uses Elna switches as far as I know....

The resistors are SMD type and many people prefer the Dale..

So I see also no reason to change this pot.

 

[miguelnoda]

I want to clarify just what the bridge is the zener diode, because they put it,
and the zener and resistance in Q5 had told me to stop.
I imagine you've probably seen the pictures, if you do the shipping.

Miguel Porfavor, contestame en Español.

Hi Miguel,

Please mail me in Spanish, I don't understand what you mean.

Thanks,

the elna are superb quality, especially for the money and if you contact them directly you can customise the stops and switching behaviour. if you want to bling it up, find the positions you use most often and replace the smd resistor with ASMP texas components naked Zfoil SMD resistor. its better than DACT imo but similar to some DACT models, maybe even manufactured for DACT

Hello forum I've seen that say termisthor is 10 ohm and 3A.
I bought it but that value has to see that this is cracked
NTC CL-60 and 5A. you can put 10sp010?.
thanks

But supposedly would have to be 10 ohm-5A, I bought 10 und 10 ohm and 3A.
that was what I saw in the forum but the one is the CL-60.
THANKS

hi do not know if you need to connect the pins of the XLR inputs or outputs
do not make noise preamplifier. how to use the bridge output
connecting a CD takes XLR shorting the XLR output.
Someone could explain this. thanks

 

[Nelson Pass]

The input XLR needs to be shorted pin 1 to 3 if you are using RCA inputs.

No shorting pins on XLR output pins.

 

[miguelnoda]

because there may be blowing or background noise in the preamp at low volume?
Since I can only change the IRF610 which incidentally are heated much 3.3K resistors, out of print for any use which has, I could help and not to do because the voltages are OK.
Greetings to all.

 

[Zen Mod]

this is third thread you're opening for same preamp with same problems .

conclusion - either we aren't capable to help you because of language barrier , or you aren't good enough in electronic to repair it even with our help ;

take that jewel to someone who knows what to do

pass labas x2-1

thanks for answering me and tell me that no repair.
I still have the problem of heating-R401 R301-R302-R402 and the measures are on its banks, the problem is that you have background hiss
low volume, you should change the IRF610?
THANKS

hello
anyone know if you can turn up the gain to PASS LABS X2.
