PFM Flea
And here's a pic of the dedicated PSU. I used a ready-made module and modified it with schottky's, a nice big cap and the right tranny and a 24V regulator. Now that I think about it, in the end I only used the PCB...
. So the Flea PCB gets a regulated supply. That makes it a pre-pre-regulated supply, I think 
. Nice and neat, eh?

Re: PFM Flea
Nice - I like it. Hard to get the components ?
Now - get it running and do some listing.

Re: Re: PFM Flea
Thanks. The components weren't hard to get, but I had to wait until I scraped together enough parts for a Farnell order. I will do some listening tomorrow evening, can't wait. Almost nap-time now ...

What's the OPAMPS on the BDs ? AD8620 ?

Re: Re: Re: Re: PFM Flea
Thanks! This player is a CD67-OSE. The Flea + PSU replaces my home-brew Kwak-clock PCB. I'm curious what the difference will be.
After the DAC I use an OPA124 (the one on the top) and in the filter an AD8510.
Have to go to work now...
Regards,
Ray.

Nice work Ray. Hope the extra work as brought more gains

Re: PFM Flea
Tasty smal PCB Ray. Only 25V for that 1.000uF?
Can I interest you in a 48 drawer cabinet with carbon resistors?
My stock is too large

Re: Re: Re: Re: PFM Flea
Thanks Brent. I'm hoping to find that out tonight.
I expect it to be better, because the clock is now running off a separate PSU.
Nice eh? I got it from Conrad. It's a small 78Lxx supply originally, but I took (almost) everything off and transformed into 24V. By the way, look harder: that cap is a 1000u/35V ZL.
My resistor stock is just fine, thank you.

Re: Re: Re: PFM Flea
mica's and styrene's
you and Brent must have cornered there market on mica's by now
are the reg's version 2
"vari-rayulators"

ps
I like the "state of the art" opamp for the headphones

Hi Allan,
Yes, Farnell is out of stock on 120p mica's now.
The "Vari-regs" are version 1.0 actually. I bought the PCB's from Eddie Wang's DIY site a while ago. But he seems to be out of stock, so I decided to make them myself for the next player, with fixed resistors. They are now known as:.........the "Raygulators"!
"That poor 4556 is all that remains"

Ray.

Hello all, im a newbie here and just want to thank everyone for the wwealth of info available on this site for cd63/67 modders. I owned a cd63se years ago which I had done all the usual mods, caps, opamps...etc. It eventually died and I switched over to vinyl for a while. I recently got a great deal on a used cd63 and Im thinking about doing some mods on it. I am going to gather all my spare parts and see what I have and then place an order to digikey and get what I need to do the basics. I plan on just doing the basics to start, upgrading the lytics to panny fc+bypass, schottky diodes, opamps, damping of the chassis....etc But down the road I would like to take the player even farther and add a clock and better regs and even maybe an external PSU. I have an extra tranny from my old cd63 that id like to use, im just not sure what for just yet. Also wanted to ask if anyone has treid out Burson audio products?

Hello Everyone
I just finished the Servo HF RF Motor Driver mod from Brent mod list. I used PRP 1% precision resistors,Caddock 1%, Black Gate, and silver mica caps.
I didn't do the RF amp PCB yet I wanted to here what changes there would be just to the main PCB, and all I can say is WOW
increased detail tighter bass I am going to give it some more time to burn in it's been about 4 hours now.
Regards
Dave

Excellent mate. The servo mods really do bring the finer details out.

Hi, and welcome to this thread. The CD63 can be lifted to great heights as you may have already read. Good luck with the mods, and if you have any questions or encounter any problems, feel free to post here.
Never tried Burson myself, I see they have some products called HDAM
. How ironic, the HDAM circuit is the part we've been bypassing lately . Maybe it can be a nice replacement for the opamps? But if you are skilled with the soldering iron I would recommend fitting a FET/transistor output stage & passive filter instead. Much more fun and cheaper

Ray.
