Pass XA25?

No expense spared on the rectifier bridges it seems. Just quickly looked at what those critters or their like go for, and was shocked.

thanks nice writing you should contribute to a magazine 🙂

Thanks!

Cost is high for not soft recovery bridge 🙄

Me an idiot. I see now what you guys mean by hockey pucks. So they are output devices.

Yeah that two fat IXYS mosfet's push-pull amp stage.

Back to bridge theme this one is interesting

Ordinary diodes bridge with snubber don't cost that much 🙄

Yes, I have some FRED diodes in standard TO-220 packaging, but this SOT-227 B packaging for diode bridge looks very interesting and promising. I have made a note of this specific part that you posted.

 

[Soundhappy]

I am guessing we will see bigger versions of this amp at some point 🙂

I am also wondering what those big resistors are for ?

Nelson can you drop us a hint or two ? 😀😀😀

+1 Please Mr. Pass

That are the ones I used in my VFET/X Soundhappy. They do a good job. Though I don´t claim that I can hear a difference with others bridges 😉

I think Henryve was about bridges because some one write (-) (+) on them.
OK they are fat mosfet's P and N channel's and mysterious orange resistors 😀

All basic stuff, nothing mysterious here, but if you want tips, you've got 2 chances.
Hahahaha

 

[Soundhappy]

All basic stuff......Hahahaha

After DEF we get Hahahaha the ultimate amplifier of joy.
Parallel push-pull for biger smile.
Field of silence are the best friend of wonderful music.
Basic stuff ok so write the right answer are complicated 😀

Hahahaha

Give me two chances......;==))

Hahaha.
You have an unfair advantage.

 

[generg]

I am not aware of it.....:--))

Simply tell us your ideas, or better only to me.....

 

[plasnu]

I really like the red, blue, white color scheme of the cables.

 

[henryve]

It's easy.

The wires going to the orange resistors comes from the cap boards of the PSU. The conclusion is a simple one. 😉

 

[generg]

CRC....:--))

 

[Zen Mod]

with Pa ....... it's easy only post hoc , always

(why I didn't think of it before ?)

 

[generg]

That is true!

But we were warned, look at SIT PSU.

:--))

Bipolar (+)(-) psu= CRC||CRC parallel for mono channel.
Ah ok that explain 4 power resistors in psu. One possible answer.
Not sure what components are under of front end pcb maybe bunch of mox 0.47 R resistors ?
See the right and left side of psu capacitors we get few components in relation with hockey puck's power output stage.
Made specialy for not 4 but 2 pcb's stereo amplifier design haha 😀
Me crazy about all Pass Labs elegant work
