Hello every one

I have an Oppo dv 980 h and i want to replace the swithcing power supply with a stable and bigger one

The 4 outputs are -12 +12 -5 +5

Any ideas?
Can i buy one or do i have to do it my self?

Thanks

Perhaps something like these Dexa regulators:

If you want to completely replace the switching supply with transformers and linear regulators, you may want to check the Twisted Pear website at http://www.twistedpearaudio.com. Get two LCBPS and two transformers, one 2x9V and one 2x15V. This way, you also have complete separation between the analog and the digital supplies. You will have to verify yourself if this can supply the currents needed by your Oppo player.

With the Dexa regulators, you still need transformer, rectifiers, caps, etc., which you have to put on a board. However, the Dexas should give you lower noise and lower source impedance at high frequencies. By how much? No idea, I have never seen any comparative measurements. Are the sonics audibly improved? Again, I can't say since I have never heard of people doing a direct A/B comparison.

Lionking: Do you have an update on your Oppo mods? How are you liking it in general? I see the DV-980H going for around $120-130 used and am thinking about it.

Alright, I have a 980 on its way!

Anyone have any specific mods for this player? I won't be tearing into it for a while, but it would be interesting to hear about some choices.
