Rotel Processor
Hi There,

i need some help with upgrading my rotel processor.
I'm using digital input, so I'm starting with upgrading the analog output section.

I have the schematics, and made a short version of the signal flow.
See attached picture.

There are some things that IMO can be left out:
- First is the cinema EQ
- maybe some coupling capicitors? (there are 5 of them in the signal path)

I allready updated the Opamps for LME49860. All the capicitors in the signal path will be replaced with MUSE BP ones.

There is also a mute circuit at the end. Can i leave that one out to?

Thanks in advance for your help.

best regards,

Hi Koenjer!

I'm thinking of improving the analog section of RSP1068 was thinking of replacing the TL072 for a OPA or AD op amps but I see that you thought in a LME49860, I think that's good, what is your experience? and made ​​the changes? have you thought about putting the LME in A class? I am very interested in your results.

Best Regards
