TDA 1541A S2 and caps

D.A.R.R.Y.L. · 23rd January 2006, 05:52 PM

Hi all,
I have a question about your experiences with decoupling caps in conjunction with the TDA 1541A (S2).
I own a CD-7 Marantz which I am in the process of modifying.
Already replaced the output caps with great result!
Now i want to change the decoupling caps surrounding the two TDA 1541A S2's.
Below is a picture of the current caps (orange ones) with a value of 0,1µF 100VDC Film.

What would you advise as replacement upgrade? Wima MKS-4 or FKP?
Or something different? I found some reference to put a higher value cap on the LSB and the MSB (Kwak and Loesch). Could someone maybe explain why this is?

Thanks a lot.

Regards,
Ramon

Hi,

those caps look like they are already big enough, but they could be closer to the S2...

Hi,

Those decoupling caps looks like Philips "orange drops". Someone stated here that they sound best with TDA1541A.

I tried many diffrent caps and indeed my favourite were orange Philips MKT caps similar to these, but I got best reults with 0,56uF and 1uF values. Niether diffrent types of Wima nor Ero were better than Philips, but I haven't tried any of audiophile polypropylene caps. Maybe some SCR or Audyn KP-SN will be better.

OK, thanks.
What is the theory behind a larger value for LSB and MSB?

Don't think they are philips mkt, I recall the prints are on top of cap for those mkt. And they are much thinner than the pic show for 0.1uf.
So better not pull them out of the Marantza and certainly don't replace them with wima mks. Some very high quality japanese caps are not known outside of japan.

I won't then ;-)
I am still interested in which caps these really are.
