Default marantz 63/67 mod

Hi Malefoda, i just wonder if you can show me how to mount the separated regulators for the 12/5 V. I am confused and unsure where do you take the postive voltage ,ground and pin out mounting in regard to the player. Also if you can show a picture of the coax mod from RF to HF-Sorry i just have no idea where and how to mount things without a picture. Much thanks .Quan.

I can: just split rails and feed the analog section of the DAC with OEM Tx with a Rayg,
have a SCal Reg on this,
Have a separate Tx and a Rayg,
Separate TX and SCal reg...
The aim is not to go too far in a part if the state of the other parts won't show the benefit of the top part (I think It's not so clear...).

Thanks guys!
Matthieu

Also a questiona bout SCal Regs here for those who had some help there:

Hi Matthieu

With out being biased The dac analogue really does benefit from the SPower reg, Thomo and Simon have found the gains to be big. Treat yourself

Quan, right now all my regs are in the normal position (and number). Coax mod is the classic one! There's a drawing of the PCB and where you may solder the coax in this topic. If needed I'll do some pics.

Thanks Brent, maybe it's "fatser" to order one of your SReg than waste time & money in a Rayg, then upgrade...
So if not too much for the rest of the player I'll tap power somewhere in the player (I guess between the 7805 and the big cap feeding it (C813?)).
If the customer I'll be is satisfied I'll see for more

Thx!

The +10V supply before the 5v reg will be fine until you have a dedicated psu for it. Solder the output pin of the reg direct onto U199 and cut U200 to remove the original 5v

You mean it's ok with stock 10V or I must have a dedicated PSU (wich maybe the same for opamps...)?
And I saw a customer comment... strange It's Simon Do you have any real happy customer? I'm kiddin'

Oh I've just read your answer again and understand it, standard 10V is OK until one day I can afford a PSU... so you're tryin' to say I should test your famous PSU instead of a SReg? Super salesman!... =)

Haha, well the feedback is for real. For low risk just buy one reg: for the DAC analogue pins.

They're good regs so should (and do) work ok from a shared supply (but of course even better from a dedicated tx - for the full dynamics and bass weight in particular).

Thanks Simon

Yes fit a reg first and run it off the +10V. Then in the future you could add a psu.

Matthieu, buy an SPower. I did and think it's brilliant, far better than the Audiocom Invisus on dac analog. It was easily one of the best upgrades I have made.

I haven't modded my player for about two-weeks now, since the discrete stage went in (a record length of time). But have made myself some interconnects and am very happy with the sound of my system. Except, has anyone found the sound more closed in with the discrete?
There's a huge amount of detail and it's all presented very cohesively, but it isn't as open as the lm4562's.

Hi Lee,

Nope, not here. I found, if anything, the discrete output to be a touch more open.

The real trick, however, is in the way it sounds so flowing and organic, with terrific bass.

I used what I would call mostly premium parts. Remind us, what parts have you used in yours? The obligatory coupling cap could be a factor here.

Simon

BG STD Supply caps, output cap is BG AC 6.8uF. The resistors are all vishay smt's and filter caps are Silver Mica. I agree to the flowing and organic comment. I think maybe I just got used to the more forceful opamp sound.

What do you use for the output psu Simon? At the moment I am still using the SE tx + 2200uF 35v BG FK. Maybe bigger will be better.

Lee.
