Caruso Prototype
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.

caruso proto picture....
et voila. first impressions. yes we can see alomst only a big brass piece..that was the idea...
the beauty is well hidden inside...

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

Hope your summer is good...Still think you might be on track for August?... (trying to keep a finger on about when to expect to make payment)flozki wrote: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.

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.

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
