Re: marantz 67
Lee is right about swapping them, but I'm surprised you say that the error mode showed nothing. Are you sure you did it right?
In my experience it will always show something unless it actually plays the disc, even in a working machine. (e.g., if you don't put a disc in you still get an error code of focus or radial error etc).
Odd...

Now then - shortly I will be manufacturing Servo clocks and/or servo clock divide circuits (8.46Mhz) mainly for the CD63. I would like to know now much interest this/these circuits could generate.
They will be small and compact and not much bigger than this clock pcb.

An externally hosted image should be here but it was not working when we last tested it.

Hi all,
I'm listening to my CD63 again, thanks to Brent locating and fixing some problems with my Audiocom clock, and some solder joints and connectors (yes - various problems).
I also have two 7805s on my servo chip and he's added an S Power regulator to feed the analogue pins of my DAC.
The sound is stupidly good with even more detail, control and better treble.
A suspected weak laser is causing some tracking problems (only when reading TOC or skipping tracks on certain CDs) though. I may change the laser soon.
Lovely to be listening with this discrete output stage again - superb sound.

Hi Brent,
I don't have a Marantz but just thought I'd add a little comment
I fitted a pair of your S power regs in a guys cdp a few weeks ago, it used LM317/337 types so I had to remove the plugs and hardwire to the pcb using really short leads and bypassing/removing the resistors for setting the LM's output.
Anyway these made quite a difference, very nice lowering the noise floor and improving depth, very nice regs Brent well done

Ahha, that's very interesting. I have wondered about that. The design is obviously going to be somewhat similar, but part choices will be playing a part I guess. Brent's regs have large SMD caps that pack a lot of uF into a tiny space. They can also deliver something like 6amps current (with large heatsink) which the Audiocom ones can only dream of!

Thats great! Thanks you for the feedback it's much appreciated.
Being a fellow DIYer and audio engineer I have designed these regs to give high performance for little outlay. I designed them to be comparable to the Audiocom QPower but have the practicality of the Super reg.
