Missing clock ?

Thomo · 7th October 2007, 08:41 AM

Sorry, I didn't realise that you had replied, so I deleted the post.

Solved it, it was a missing 22n cap from the decoder. My mistake (again)

Cheers,

Lee.

C514 acts as a filter, together with R514. You could upgrade it to a polystyrene if you like.

Thank You Ray

I will report my mods.

OMG - if a Scot tells you that you are cheap that is baaaaad.

My grandad was a mixture of Scottish and Jewish. If you believe in stereotypes, that would make him the tightest tightwad on the planet.... and he was!

There are several clock circuits around which do no use a comparator. Remember that (at least in the CD63) the clock replaces the crystal which feeds into fast gates in the dac chip.

Definately an sonic improvement and you can 'upgrade' to the comparator later.

Although I have some Yorkshire blood (and am married to a Yorkshirewoman!!) it's not enough to stop me using the comparator.

However it is enough to make me build it myself instead of buying (sorry Brent!).

Just one more question please Ray.

The link from your site to download the eps format of the clock pcb doesn't seem to work for me.

Don't think it's anything I'm doing as I got the CD outputstage eps fine - opened in Photoshop with no problems at all.

I've nearly finished building it on tripad stripboard from Maplins but it's been a headache working out the connections for a novice, with trying to construct a groundplane out of the spare strips, and I thought I might try having a go at etching a pcb.

By the time I've bought a starter kit for about £12 from Maplins I could probably have bought a pcb but don't know where to find them on the net.
