Marantz CD63 & CD67 mods list

[craigtone]

Thomo - I love your avatar! We have one full-blooded male JRT about 4yo and a mixed female about 3yo. We love them to death! Like living with a 2-year old ... always into trouble and fun personality!

Sorry off topic!

 

[SimontY]

Haha, they do look like really cheeky dogs!

 

[Thomo]

They're the best dogs. So much attitude and intelligence, there's never a dull moment!

Cheers, Lee.

Hello to fossil2K

Hi fossil2K,

It will be good idea if we group-order from Brent (Sercal) for the clocks, etc. from UK. You can contact me at Penang 016-4524202.

Cheers,
Simon

Penang is that where the Penang curry originates from? I love it!

Sorry OT

You could always come to some sort of reciprocal trade relationship ... curry for chips?

Clock kit

Hello
I recently purchased and assembled a clock kit for my fairly well modded 67, i know should've done it earlier but the problem is this, on the board the input is marked as 12v a.c. I'm no expert but this seems odd. This was bought from China so can get no help through email. Otherwise ok - oscons, 317t's etc . Not even sure what design it is, but looks a bit like a flea?

Any help from this brilliant thread and its members would be most appreciated.
with luck a pic will be attached

Well I can see a surface-mount bridge rectifier, so the AC input is not odd.

I wonder why there is a trim-pot-like adjuster under the screening can.

The suspension/isolation is very cool!

Overall it looks very simple and is probably not quite up with an Audiocon Superclock or Sercal C1, was it cheap though??

Ah, on which case where would be the best place to tap of for now? as i understand it will feed pin 28 and grnd.
Thanks for that Simon was going to run of a dc transformer eek.

 

[ian21]

Yup £20 plus £2.50 p&p from China took 5 days

12Vac is correct. You need a 12V transformer.

Simon the trimmer is to adjust the freq spot on, it should already be set so do not adjust it.

Thanks Brent
A Maplins job for now.. just to test? or something more 'bespoke from the start... as long as its regulated?

Woweee that's cheap. A Fleebay item was it?

(Ah, I wondered if that's what the trimmer did, thanks.)

 

[SimontY]

Thanks Brent

The rectification, smoothing and regulation are all onboard by the looks of things. You just need a small transformer, or to find ~12vac from the CD63 transformer.

 

[ian21]

Yes try' low jitter clock' using the worldwide option... thought i'd take a chance.

 

[SimontY]

And why not, saves some cash

I'm thinking of trying a headphone amp or pre-amp from one of these Chinese cowboys.

Thomo can sort you out with a good transformer @ DIY AUDIO

Email him asking for a 12V 7VA Nuvotem. I know he's started stocking these and they are superb.

That looks really good! Line-level op-amps don't seem to like headphones all that much, but I see the Meta 42 has a separate output buffer IC....

Thanks for the suggestion!
