Pass XA25?

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 :rolleyes:

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.
 
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 :D

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 :D

It's easy.

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

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 :scratch2::D
Me crazy about all Pass Labs elegant work :superman:
