cheers lads, it does look a whole lot different in a picture than it does in real life. Im loving the sound now, and yes simon, i will leave it alone for a bit.

Only thing to put in this next week is the 5V reg board. Then im done until at least xmas

AS for music, im bidding on 'The battle for los angeles' on ebay atm. Good old bit of 'Rage' to see what this baby can do. Will also be buying some 'OK GO', 'Wolfmother', and 'Nerina Pallot' to have a good listen to !

Just found a couple of varistors in my spares pile. Farnell #318607 - any use for trying out on the incoming mains supply to the player?

Cheers

Greg

Sorry it's in 3 parts !

Allmost there with post4464.
Excellent!

The grounding after each regulator shows a string of low resistances from the reg 0v to the caps....
All these parts are wired point to point by their own leads. I don't think I can realistically improve on this.

Quote:

I disagree on the E to CDP star, keep the 6r8 and add 10nF or 22nF 250V cap in parallel.
I'm not sure who you're disagreeing with. I can add such a cap. Although for the first changes I will leave this safety earth connection in (and make sure there is nothing else connected directly ie. psu, power amp, pre amp, x-over.) I do have some hum that needs fixing.

Quote:

How low is lowDCR in the little inductors? 50T of 0.6mm enamelled copper?
My meter reads about 2 ohms. I'd say fewer than 50 turns, probably more like 20. I measured the inductance but don't have it handy.

Quote:

Please give us an update on the sound effect of each series of changes, particularly the ones that don't work.
You can be sure I will!

1 - I will start with CDP connected directly and the psu connected via the network you proposed. I will assess noise and hum levels.

2 - I will disconnect completely the psu star from house earth and assess.

Hopefully progress will have been made by this point and not to forget I will be disconnecting those other earth runs from psu to cdp and installing a large earth jumper between stars. I take it you agree with this part?

Cheers,
Simon
