240v Seduction

[Zacwah]

Hi everyone,

I haven't built a kit yet but i'm waiting for the Crack to arrive. In the meantime i've been eyeing off the Seduction preamp for a vinyl setup.
I don't know much about electrics and was just curious if it is possible to wire up a Seduction so i don't need to run it with a step down transformer (240v to 120v). Also if i had to run a step down transformer could that introduce noise to the system?
The fact that its stated that it only runs in 120v is a bit of a deal breaker for me.

Any help would be much appreciated.

Cheers.
Zac

Zac,

The Seduction transformer does not come in a 220V version.  

The Seduction doesn't draw much current.  A 500VA or 500W transformer will be fine, actually overkill.  It should not introduce noise, in fact the induction of the extra two windings might block some high frequency noise.

Thanks mate.

So something like this should be perfect? http://www.tortech.com.au/product/500-watt-stepdown/.
Might have to go order the seduction now.

The 100W one for $30 or so would work fine.

Too easy..

As soon as i successfully complete the Crack i will be ordering a seduction.

Thanks guys.

When I came upstairs I checked and my actual calculation would have said 120W.  But Doc know best.

W=VA
High voltage circuit draws about 25mA at about 135V, so about 3.375 watts
Heaters draw about .73A at 6.3V, so add another 4.6 watts
Looks like about 8W to me, but it is about time for my martini, uh, medication.

I just plugged my seduction into the wall with a "Kill A Watt" meter in line.  It's reading 124 volts, .08 amps, and 9 watts.  Must be some rounding in some of the displays since the volts and amps should give you 9.92 watts.  

Either way, You won't be stressing that 100w step-down transformer very much.

My seduction has the C4S upgrade.

The difference between VA and Watt is typically refered to as Power Factor. The usual suspects provide good explanations.

It's basically AC (rms) vs DC, and it's close enough for jazz in this case.
