Adding a Mundorf Silver/Oil Cap to Arcam FMJ P7 RCA Input?

[soundengine355]

Hi,

I own an Arcam FMJ P7 Amplifier (7x150W/8) and was wondering how I would go about adding a Mundorf Silver/Oil cap to the RCA input,

I've seen number of DIY amps add a 3.9uF cap to the RCA input.

I've spoken to a couple of DIYers and they said anything higher then 2.2uF will do the job, how do I work out the right uF? or do I just try and see?

How is it connected? Just to the positive input? or is it the negative?

Hey, you made me check the calendar but it seems it's still not April 1.

I guess you are used to it everyday in SA, mate!

Waste of space 🙂 (Oh i'm talking about you!)

Maybe replacing TL072 against a OPA1612 provide better sonic results.

Why would you want to do that?

Perhaps you should repeat your question in capitals. The addressee has last posted 10 years ago 😛
