Re: Focusrite Saffire Pro 40 re-cap

Ok so my first attempt at replacing my op amps went horrid. The SMD station got the Op Amps out with no problem but the tip on my solder iron was way to big for the job and ruined all the pads on the first and second channel. The only way to recover at this point would be to trace where the damaged pads go and run wires to the op amps.

The elctrolytic recap process has gone fine so far with no problems but those op amps are so tough to replace!

Awesome, so what would you replace those 10uF/16V caps with? I am guessing they are decoupling caps for the AD/DA chip?

I was thinking of changing to maybe 47uF/16V

Re: Focusrite Saffire Pro 40 re-cap

Here are the caps around the AD/DA chip. They are all 10uF/16V.

I'm wondering what I should change these to?...

Thanks!

So I've got the hot air rework station ordered as well as the LM4562 Opamps... I'm clueless about a few things though

I'm not sure witch values to change what to as far as caps go because the layout is totally different on the pro 24 vs the pro 40.

Basically my biggest complaint with the Saffire is the high mid frequencies... The feel very unfocused and somewhat "mushy".

I used to own a Lynx Aurora 16 and loved the way it sounded, it was very...

Re: Focusrite Saffire Pro 40 re-cap

Cool,

I am just going to change all the opamps and 2122's with LM4562's. I know it will be pricey to do them all but I don't mind spending a little extra and I'll feel better about it. It sounds like the caps make a big difference too. I will replace them all.

I have been doing regular soldering for years but I have never done SMD. what is the best way to get the components off the board? I'm going to buy a rework gun. Also what is the best temperature to operate at? I would be a little worried to damage the board....

Re: Focusrite Saffire Pro 40 re-cap

Hi,

everyone, this is my first post here. I have a Saffire Pro 24 that has the same OpAmps you guys have in the 40.

I'm planning on doing the mods. Is there any BurrBrown chips I could use for the opamps that would fit instead of the LM? I know BLA mods the Saffire and they use BurrBrown chips.

I also checked out the AD/DA chip.

Also noticed the CapXon caps, those are coming out!...
