I know you are most probably right Kevin, there are CDs where that would not work.....

Anyway it's worth a try, i know of some old PC keyboards with hall effect keys so it should be easy to try out some variations on the theme.

Today I really made a giant leap forward...
Despite Peter's findings with the tent clock I had a thrill with installing the Trichord no. 4 ...

At the moment I made use of the 8V reg supply to supply the clock I will build a dedicated..
(with help from my audiofriend...twice the fun !!!).

This takes the transport to the next level and is making it a serious contender for my Wadia...
The synergy and the beautiful anologue sound remains....but you get it in spades...

I used Eva Cassidy and the live feeling ...clapping hands...steel string guitar...etc gets more detailed and less edgy...
Instruments get more body...(something I thought would be only the case when supplying the chips seperately)

The Jolie Holland gets considerably more PRat (which it really needs otherwise it gets too bored)

I urge you to experiment...for me in my set it delivers....

....this is not only a zero figure for science...
(clock-speed-deviation indication on the Digital Lens)
I can translate it back in the music on my set.......clock at the proper speed works for me...

Here the clock in motion and I made a complete Ebony coupling while I was at it (together with my friend Anton)..which sounded very rich for me...it probably will stay my way of coupling...

Interesting, perhaps I will try an outboard clock at some point. I assume this one has a local (5V) regulator?

Well today i got a pleasant shock, i warn you first that this is a little long ion the tooth for some of you more experienced DIY buffs but i like pictures so Ive got a few for you.

A friend of mine turned up to day from his work travels with this for me

On my search for a compatible unit ive picked up a spare laser rack and gear plate with motors, the PCB was no good but these will do nice for spares. It also has a nice small pcb with the laser stop switch mounted to it, this is going to go on my new unit.

One thing im unsure of, the older motor has a PS1 type CD clamp with the bearings to hold the disc in place, which would be the better choice the puck or the ps2 style clamp?

Erik. Have you replaced the original crystal oscillator (E7 on Okapi's PDF) with the clock ?

Default beware

Kanifee,

i have tried to use an equivalent mechanism to yours with the original ez31b control board.

i had some problems so i am curious to hear about your results.

i found i had to return to the original servo/laser of the ez31B because it would not work at all.

now i am using the original laser with the other motors but i have frequent tracking problems. i plan to switch the original motors back in sequentially but have not done so yet.

please keep us updated on your progress.

thanks for all the pics as well.

Erik,
I’m not surprised of your clocking success, I run my clone with external clock with separate psu and tranny since several months already, and there is no way back.
Btw. Funny thing, Eva Cassidy’ Live at Blues Alley was one of most plaid when tweaking my clone

Okapi, im still using the original laser and motors, the only thing i have changed is now i have a new pcb fixed to the bottom of both motors that includes a laser stop switch so i don't need to extend the reach of the original one to raise the whole mechanism above the main psb board.

Any advice on the CD fastening heads on either assembly and which would offer greater results?

I have had the unit up and running with the old psu and psu motherboard and all seems fine, skipped tracks both ways to check laser tracking, hard reset the unit to make sure it reads the disc fine and all seems ok, one thing i noticed is hooked up to my lm3886 amp through analogue output it seems awful low at full volume, will using an external DAC cure this. lastly what sort or prices are external clocks and what are some suggestions as i have absolutely no knowledge of clocks.
