Hello,

My friend want to have a chipamp for her iPod.

As already have a couple of LM3875 around, could you adivse a chipAmp (w/ pre) that can be driven directly from iPod?

Thank you very much in advance.

Cheer,

PS: I have no idea about this iPod device.

Is that the mp3 player that drive headphone? Any special buffer needed in this case?

I have an ipod and have hooked it directly to my gainclone. I have the 3875 kit from Brian and it worked great running right off the ipod.

And yes, the ipod is an mp3 player

Hi ejn327,

Could you tell me more about your 3875 GC? As standard PD's GC?

- Gain: 22K / 680 Ohm
- Rin: 22K
- Cin: 4.7 UF
- C pwr: 1000UF

Drive directly with 50K pot.

Will it work?

Its the 3875 kit from Brain at www.chipamp.com with 2 amps per channel in parallel.

Not sure if what you have listed will work or not, as I have no idea about the amp design. I can only put them togather.
Most of the values you show look similar to what Brian's kit has.
