I only have 3 LM opamps. As I am using 5.1 speakers, do you know which of the 3 surround op-amps should I replace?

2x OPA637BP, Rubycon Black Gate NX 1500uF 10v:



DAC / Front OPAMP / Crystal Clock recap awaiting .
I should be also getting Yamaha HTR-6130 receiver soon. I have 2x sick bookshelf speakers on old amp atm.

OPA637 is without a doubt best OPAMP out there, it sounds just perfect.

Is there someone willing to mod my X-Fi? PM me if you are interested. I would prefer someone in the US.

Does anyone know alternative soldering spots for muted transistors?

The red dots is where the pcb ripped off:


I'm guessing the green dots would alternative spots?

Does anybody know what is the mapping of the second Opamp(just below of L-R one), what channels does it control.
While removing the old opamp, I removed the solder pad underneath one of the pins. Now, one of the pins of the new opamp, remains without contact. Is there a way to save my xFi?

Find a handphone technician, they are good at small part and use a blower solder.

looks like you could change the op-amps and coupling caps pretty quickly.
post #1871 of 2194
Which one ?
What pick from AD 8599 or AD 8066 or LM 4562 ?
The caps - what type and brand ?

I use 3 diffrent opamp in my x-fi AD8599 for front (the best n expesive one), AD8066 for center/sub (softer then ad8599 but give more bass) and LM4562 (too Sharp for music but it's the cheapest one) for surround..it's your call, every one have their own taste
For the cap i use Nichicon FG...well at least it's all i got
If you want the best, use Rubycon ZL for c177, Elna cerafine II for coupling (soften your sound - or short it for as-is sound), Panasonic FM for c46,c72 and Sanyo OSCON for c119

All that 3 op-amp are compatible pin to pin with IC from Xfi board ?
And for that model of XFi what IC is for what ? ( front / rear / cen + sub / side )

Normally the 2nd chip from the top. Don't bother unless you're a soldering genius though. I've been soldering things since I was 8 and I wouldn't attempt it, so many things that can go wrong, especially if life doesn't want you to do a good job.
