Hard times

Ahh, the joys of modding..................

I know only too well how you feel, and so does Simon...........

You wouldn't be a true modder if you'd never experienced the frustrations - as soon as you've made the mistake you realise you knew better and shouldn't have done it.

But.. a moment's lapse in concentration and you start calling yourself "you stupid b******!" etc

Regards,

Jim


PS Only joking Simon me old mate!!

Well, this time things where not that bad.

I managed to repair the pcb when replacing the faulty sreg.

At the same time I needed to redo the connection for the star GND (loose), so I decided to remove C803 and C804.

Now I only have 2x10.000uF Nichicon before the +-12v regs.

Inittially I believed I heard less bass... but after some burning the sound is more detailed.

All this was needed to save some space for the clock PSU.

It was difficult but the outcome was ok.

Thanks to you all I hear the music again.

Ricardo

Less caps on the analog psu, before the regs, added some detail and speed in the bass.

Didn't/don't you have a slightly over-the top-capacitor array? I think with that level of capacitance you might introduce noise into the circuit and are finding improvements here and there from good smoothing but also hearing the effects of problems it's possibly causing.

If you can't spend a lifetime learning how to model the theoretically perfect power supply, then a high level of experimentation makes perfect sense. I always enjoy reading your comments.

Good luck Ricardo. The clock psu is a nice one indeed, particularly for timing / PRAT and soundstage.

Simon

Voilą !

And I'll move regs closer to opamps when I buy Sercal's stuff.
Enough work for now

Music!
