It's almost a GaN laser. Use protective eyewear.

Speaking about music, I'm listing to Jack Johnson right now. Sweeeeeeet - with the LM4562. Really transparent.

I've just tried what you said and the beam went straight through the ceiling and roof and is pushing the moon out of orbit.

This is definatly and improvement in audio over a small pcb with 4 regs and small toroid, trust me i've built an millions (err alot anyway lol) I'm sure if i could squeeze this psu into the unit then the benefits would be greater. This psu does have a rather large Toroid in it.
So basically two identical psu with one inside and one external the internal one will give better gains. But a good external will be better than an average internal IMHO

Hi.

External power supplies are nothing new. One of the original articles on modding the CD63 used one.

http://www.acoustica.org.uk/t/63/63hacks3.html


Maybe it provides better mains filtering due to the large toroid?

I wonder if the extra power from the external power supply is just the power the metal cutting laser LED???

I have them, both in the 63 and in my pre (kind of ESP project88 but not quite).
Ahha, well they are certainly nice, just yet to see how nice

Yes, my HDAM is removed. From the op-amp, there's just a carbon 33ohm resistor and straight to the upgraded output sockets. It's pretty nice sounding.

I installed a new XO in my Marantz Cd-53 MKII. It worked very well with the power supply recommended by Guido Tent.

When I try to build a better PS with this schematic http://www.acoustica.org.uk/t/naim/35clockreg.html
The CD player refused to work even though the voltage supplied is measured at 5V. ( I use 1/2 of NE5532 instead of AD797)

When I switch back to the Guido Tent's PS it works fine.

Can anyone explain this to me? Is something wrong?
