zenelectro killer clock
« on: August 03, 2011, 02:14:42 PM »
Today i received a prototype version of zenelectro killer clock currently running in very promising i actually prefer it to my clock  :'( its a cleaner sound without being analytical texture colour of music is still present imaging is also better.Honestly its the first clock i had in my house that cuts the mustard without modding/tweaking.No fancy duelunds caps used just great desighn work done with a educated guess.

Zenelectro is working on it now custom made boards will be made

I decided to put my clock back on for a listen my clock uses a dubilier 8uf and a duelund 2.2 Approx value $300 in caps
Didn't take long to put zenelectro clock back in,zen clock is more opened less veiled it just sh!ts on my clock.
ps:terry i hope you know that the zen clock is staying on a holiday in perth :D

Great stuff!   Any actual tech info about the prototype would be nice if you are willing to share, zenelectro. :)

Great news , maybe I could fit one to th A-gd to stop it sounding like sheizer  ;D
Seriously though, I would love to try one.

Great news indeed! Been looking to upgrade my clock and this is very promising! Registering my interest now  :)

Big news.   Good work getting the prototype out Terry.

Cant wait for the production batch to roll around.   My hand is up for 1.
It's all about the music,, not the equipment.

The best way is to contact zenelectro via pm as your transport uses a dvd player frequency from memory 27????mhz,

Thanks Mario / guys

The goal was to make a super low jitter clock that had the usual attributes of imaging, detail etc but to retain
(or maybe even enhance) the often lost qualities of great musicality and natural timbres etc.

The design is a pretty all out approach with every function block having it's own separate VLN discrete reg.

The oscillator itself has super low jitter spec (rms < 1pSec) and a phase noise spec of -120dBc at 10Hz from carrier (11.2896MHz)

Whilst the specs are very good, the main focus as stated above is a design that retained musical qualities that can get lost when clock are upgraded.

I'll also be trying one on Stevens system to see how it translates and help get a handle on it's performance.

I'll sort some pcb's and get a small batch of 11.2896MHz clocks underway.

cheers

My clock is a fully worked early tricord, that even standard, i feel is better than tricords current design. There is very little left of the original clock parts. I even think the earlier crystal is better than his currant one and i use it. I use duelund caps sidereels caps, tantalum resistors,  all battery powered, It has timber, body, warmth, involvement, beautiful mid range weight and rhythm and pace, not analytical in any way. and it is head and shoulders better than any i have heard, so it will be an interesting test.  Remember Terry had a lot of imput into the killer DAC, so from him, i expect greatness.

This sounds a most interesting development indeed.  Will be following further reports.

No worries V.I do think it sounds excellent but am still interested to see if it could be improved with the new clock.

Just a quick update i have installed a duelund on the clock on the input of the 12v car battery,nothing like a duelund very very good.
Vitavox will be coming down for a listen on the weekend if anybody else would like to come down send me a pm.This clock will be going to steve's house next monday, express post with a express post bag included for the return to my house I know steve too well so i really hope it doesn't perform well on his system or i wont be getting it back for a while.
ps:To stevenvalve all the postage costs will be covered for the return of the ZEN clock to where it belongs  :P

Interesting how it can be taken further by top components surrounding the circuit, some times electronices  with even bog standard components can sound good.  A Marantz 7 comes to mind.

Make sure Steven remembers that, last time I did the same thing, sent a package to him including two unused express post bags, you know what he did to the bags? He chucked them away coz he thought it was only for paddings! LMAO!!! :D

Thanks for the info Terry.

Any chance of getting a 12mhz chip pretty please?   If not, is the oscillator chip easily replaceable?    If too much hassle, no problems :)

The electrolytics that Mario replaced were $3 parts, however they were used intentionally as electros are required for non
battery operation and not everyone has (or wants) a car battery running their clock.

Getting performance from AC supply close to that of a battery is a challenge but that is what I am working on now.

All good fun!

cheers

Tuyen,

Are you referring to 12.288MHz - what player is it for?

Presently I am looking at 11.2896MHz as this is most popular (to suit CD94's etc).

The oscillators are specialised and quite expensive so I need to get them in quantity to
be able to keep costs reasonable.

However I am sure in the future I will be able to accomodate more frequencies.
