rewiring a Neve 33609 compressor from 110V to 240V - is it possible?

[beesting]

hi.

is it possible to re-wire an original vintage Neve 33609 compressor from 110V to 240V? is this something that I could do or would it need to be left to a tech? trying to get a unit from US but dont want to use an external step down converter if i can get away with it - Australian power supply (240V).

thanks.

Hi

The 33609 has, from day #1, a switch on the rear panel that allows it to run on either voltage.

Now, there are "fake" 33609's that are really PL83???? (I can never remember those damn numbers!) which comprise all the audio electronics of a 33609 but are designed to fit into a Neve 81** console so run on bi-polar dc.

These units are modified by a.n.other to have ac power supplies and nobody knows how that's put together and what it can do other than the owner of the unit and the builder of the power supply.

So, your question should be addressed to the person selling the compressor. If it's a "real" 33609 it will have a voltage selector switch. If it's another module that looks like a 33609 but has an external power supply... does it have a voltage switch.

If it doesn't, it's probably possible to get a tech to rewire it it for you, or last ditch solution, just buy an OEM 24 volt power supply for it.

thanks Geoff. your help is much appreciated.

does this look like a "real" 33609 to you? apparently it doesnt have the selectable 110V - 240V switch so i'm confused. it doesnt have a serial number on the case either...

Hi Mike

Yes, that is an original from my era at Neve. The problem is that the guy didn't take a photo that shows the left side of the rear panel clearly.

On this model, the ac input was via an EP4 connector and this was modded on later models... and by users... to have something more practical... as seems to be done to this one.

The voltage switch was actually a wafer switch on two pillars spaced off the rear panel. You can't see it in this view because the ISEP 2 rail is so wide it hides it. On the rear panel is a thin black/engraved white label with 120/240 engraved in it and the voltage is changed via a screwdriver in a hole in that label.

The label is black and very thin so it doesn't show up very well in that top view photo. The rear view photo doesn't include the left hand edge that would show it clearly.



PS Look at all those luvley Marinair transformers!
