Hi Ray

I built the sreg with a 220uF BG STD on the cap amplifier and left it burning during the night with a 11v bench psu.

last night I got 4.94~3 volts but now I am reading 4.81~83 volts.

Does these fluctuations matter ?

In my first reg (built with two red leds and as a normal rayreg) I get 5.01~2 volts without dropping.

Can I use the superreg on the analog ac or should I stick to the normal reg that gives 5.01v ?

Regards

Ricardo
Hmm, it's a bit low, that voltage. It could be caused by the heating of components; the voltage drop of LEDs and diodes decreases with rising temperature. Take a look at the output voltage just after you power it up, if the regulator has cooled for about 15 mins. Is it back to 5V again?

I second that! If it wasn't for the friendly people always willing to help, I wouldn't be able to bore my wife half to death, half as much as I do. I really enjoy hearing her comments when I ask her opinions after I've been modding. They're usually not very constructive

Cheers everyone.

Mine says "After all the money you've spent on it, the one you broke and all the bits left lying around all the time you could have bought a new, good one instead of buying an old one and trying to do it up.
And you could have been listening to it in the meantime"

Have women got no soul??

Explain to her that a new one won't sound as good unless you spend over 1500 then show her the back of your hand

Brent

P.S whilst writing this the wife saw it and showed me the back of her hand LOL

LMAO!!

With three kids I've developed eyes in the back of my head.

Only trouble is, I still haven't learnt how to engage brain before engaging mouth, especially in those "delicate" moments of "negotiation" with my lovely wife!!

Can't be doing too bad, I suppose, getting a C1 and therefore the blessing to do more "tinkering", which is wifespeak for installing an excellent mod!!

Hope your local A&E isn't too busy tonight!!

Jim

Well, every time I switch it on, the value goes to 4.94~3 but after a wile it drops to 4.8 or even less and the oscilations appear.

Nevertheless I changed one of the leds to a green one and the output rose to 5.04~9 (on the bench).

I then installed it in place of U199 and cut U200. Power comes from C813.

The sound gained overall detail so I can hear better bass and more microdetail in the high freq.

Fantastic modification.... I am already thinking about powering the digital +5v on the DAC with another superreg.

Thank you very much for your help.

Regards

Ricardo
