If you ask me, SAA7220A + TDA1541A is not good.

Better stay with SAA7220A + TDA1541.

I also do not like SAA7220B with TDA1541 /A.

With non os 1541A is better.

But ask jean-paul...

...or use the search function.

and opa627 is 1 or 2 ? is it a full equivalent...?
opa627 is 24 each....
so I prefer to be sure.
thanks
Please always check datasheets as they can be found at the manufacturers sites. One important parameter is max. supply voltage ( among others ) if you replace NE5534 opamps for other types. NE5534 can take max. 22 V which is rather exceptional. So check supply voltages when you replace NE5534. In some cdplayers ( Marantz CD80 for example ) an opamp is used for DC servo purpose. You can leave that one ( mostly LF411 ) where it is if a cdplayer has one.

NE5534 is a single opamp and so is OPA627. No problem whatsoever except for the 22 pF cap that needs to be removed.

Old news but a new clock will help a lot. Check the various threads on the subject.

Using the Search function is good advice as many things tend to be repeated several times which "pollutes" the space on the precious server ( something some people don't seem to get, only the sun shines for free ). IMO it is a bit selfish to expect people will answer your question that has been posed 10 times before just because you don't like to do put some effort in it. It is also good to read the other info in those threads that may not be repeated again in a new thread.

I prefer TDA1541A and SAA7220P/B but that's just me. I listen to the chips, not to an analyzer. I also don't mix up TDA1541 with SAA7220P/B and TDA1541A and SAA7220P/A but that's just me.

I have no advice on that as I leave the originals ( 680 pF in reality ) where they are if they're styroflex/KS.

It's for a new DAC, so there's no original one

The good thing is that I cand find styroflex in Strasbourg. 0.60, I don't know if it's expensive or not.

Please rewrite your post in english everyone can understand.

You can edit your own post after posting for some time which gives you the ability to rethink/rephrase what you want to say.

Default TDA1541A ordered from Reichelt

Hi,

I ordered a TDA1541A from www.reichelt.de for replacement of TDA1541 in my Philips CD650. After reading this thread I see that I obviously received the non A version, am I right?

Fabian
