Default creek 4330 115V - 230V conversion

hello all..

my used creek 4330 amp has just arrived in the post. It's the US model (115V 50hz) so i need to convert it to my native australian 240V...

i am aware of the problems involved with foreign equipment but the the instruction manual does state:

"MAINS VOLTAGE AND FREQUENCY IS INTERNALLY SET FOR THE COUNTRY OF USE"

my interpretation of this was that the AC input voltage could be switched / set to australian current.

is anyone familiar with this model and able to shed some light on the matter?

here's an internal pic of my US 115V model:

and here's a 230V UK model (note the abundance of capacitors compared to the US model) :

hmmm - id say it's not as easy as flicking a switch?

any help would be very much appreciated - i want to switch this thing on ASAP and see what all the 4330 fuss is about

i am pairing with a couple of B&O beovox s55s by the way.

thanks

To be convertible, the transformer requires 2 primary (mains) windings. This will be shown on the attached label that can be seen in the pic. There are a few winding arrangements that may be obvious on the label....or not, if it has faded or is too brief to follow for explanation. It is not a certainty that the transformer will be convertible either, so check out the transformer.

Typically, the 2 primary windings are joined in parallel for 115V mains and in series for 230V - simple as that. However there are tapped winding transformers too, where you swap the tappings. All this may be shown in a service manual that needs to be the same as the model, version or revision you have. Schematics are fine, but are not guaranteed to deal with the possible variations of each model. They're also hard to find for the 4330 - any version. http://altor1.narod.ru/DIY_Hobby/Fri.../CREEK4330.JPG

If changing windings from parallel to series, there is a "sense" or direction (shown as +, - in the diagram) to maintain for them that keeps them the same in relation to the power connections A, N. This means if windings RED-GREEN and BLACK-WHITE were in parallel, with RED+BLACK and GREEN+WHITE joined, you woud need to be careful with rearranging them in series with a RED-GREEN+BLACK-WHITE sequence. i.e. the connnection across the mains A &N terminals will be RED and WHITE only.

It won't be disastrous if you get the sense wrong but there will be near zero output (fields cancel) and nothing works.

thanks ian.

the friendly bloke at creek has informed me it is very easy to convert it to 230V - a simple re-wiring of the mains switch and a fuse change is all that is required.

cheers

Easy - yes, as is fitting a smaller fuse but was friendly bloke also giving advice specific to changing the wiring of your model/version?
If in doubt - don't. Get a tech. or experienced DIY to assist with mains wiring.
