Caps across the diodes alone will change things, but not necessarily improve them. Here's a really good (if rather technical) read on the art of snubbing, or why you should consider adding a series resistor with the caps:

I'm not sure but I think they are talking about the clock divider circuit to feed the servo with an upgraded masterclock signal in the CD63.

Of course if anyone wants to make and sell a pcb for an alternative output stage...I'd be interested I reckon!

Hi Simon,

Boxed the player for transport yet? I expect to wreck one soon, as mods are beginning to expand 🙂 and bought a second for spare...

The problem with producing PCB's is the drilling part. It takes both time and .8mm drills 🙄

Furtermore the four inductors need to fit exactly as there's little room for alternatives.

Thanks Jaap for the link

I wonder how much it would cost for PCB's? I guest I could use the HADM section like Ray did it would take some time to figure it out. So many mods still to do however I did receive some parts today so that I could build some regs.


Regards

Hi Jaap,

I actually drove to Brent's workshop to drop it off yesterday. Very nice chap he is, and he's err, enjoying fixing it.

I saw and heard Brent's player and it is very nice indeed. Looks and sounds fantastic! Wasn't in his main hi-fi tho, so I don't know the full extent of its greatness.

I see.. The problem for me is complexity and breaking it again. To do a discrete output stage I'd need good instructions, a clear schematic, or even a pcb. Ray does say the gains are good moving away from op-amps, even the stunningly good 627. So I am of course interested in doing something there.

Goodnight all.

Simon
