Caruso Prototype

[flozki]

just a small update on caruso.

i have all important parts for the prototype on my desk.
magnetic systems built. just the drive coils to wind....
so just need a rainy day and put together the stuff and build some assembly tools.
and of course. heavy testing then....

what i can confirme now is the price for the "early bird" order list.
i also preordered some of the critical parts to accelerate a first production.

I will announce when i start taking orders. i guess i will do it beginning of august. because i want to have a easy chiller summer...hehe.

i will let you know whenever i am ready. but it looks quite good.

Thanks a lot for the news Flo!
Don´t forget the Presto 6n users, some adapter...

[flozki]

et voila. first impressions. yes we can see alomst only a big brass piece..that was the idea...




the beauty is well hidden inside...

gorgeous! august is perfect for me, keep me in the know flo! i'm definitely down for one when the time comes, just need to know the price.

[piaptk]

That looks great! I'm definitely down if they can fit on a 6n.

First opera star to take advantage of a brand new technology - the gramophone - to further his career:

"His 1907 acoustic recording of "Vesti la giubba" was the first phonograph/gramophone record to sell a million copies"

hmm
not too way behind. still have to wind the coils. thats the main task to do at the moment....

[cymbalism]

Any eta for the head yet flo? I'm dying to get my hands on one

[Nickou]

yes , me too....

[flozki]

yes some slight progress.havent worked too much on that.
i did yesterday the first measurments of the drivesystem under a laser vibrometer.

resonance frequency is exact where it was calculated. 1000 Hz..
excursion of +/- 100 um is reached with no mechanical limits.
current is approx 1 A for reaching the +/- 100um.

so all is quite as previewed and calculated.
also major parts for 10 heads are on its way.
one part i had to reject (out of my specs) so they have to redo..

also i just serviced my coilwinder and have to adapt for the caruso drivecoils.

hope to have the head together next week. and then verify the feedback system.

if all works as i want i will start with the preorders. not before.
expecting that in about 3 weeks.

Thx for the update

Hello Flo ,
many thanks for those informations .

Neumann says in his manual than the max excusion for a sx74 is +/- 150um,

and I don t know how to interpret that ... is it possible to have more detail ?
in advance many thanks
