Do'able, or ditch it?


Recommended Posts

Plenty of pro-market CD players available in USA, e.g.Marantz PMD340, that appear to make economic sense as a CD transport (not as a full-on player).

However, these are badged as 110V 60Hz.

Does anyone know whether they can be re-configured to run 240V 50Hz?

Don't mind a bit of frigging around if it's do'able, e.g. connecting to different windings on transformer, or even new transformer.

But if it's a plain crazy idea then please let me know.

 

Thanks for all input.

Now this question has been asked before and generally the conclusion is that it's not really worth it.  And not a DIY job.

 

Having said that there might be some configurations or models that have room to move.

 

When I did get a 1110v changed to 240v I arranged for the seller (in Canada) to ship it to the manufacturer (in USA) where they installed the 240v power supply and then sent it here.  Not cheap.

Motors and stuff like that are often (nearly always) dependent on the mains frequency (50 Hz here, 60 Hz USA) and this would require quite a major power change--not just a transformer. 

I'd suggest it's not worth it.

In some Turntables and Reel to Reel machines maybe.

 

But I don't think I've ever seen an AC motor, or any form of mains sync. in any type of optical disk spinner.

Or even in a Cassette Deck.

That's in my experience anyway.

A CD player should be fine - low power use, all DC parts, etc. In that space, I know a lot of the Tascam product is voltage switchable - as is my old Denon.

 

You might find that replacing the transformer is a pain and that using an external stepdown is easier.

OK, a glimmer of hope. I might do some more digging and see what turns up!  As noted by ThirdDrawerDown, "..there might be some configurations or models that have room to move".

 

If nothing else then I'm likely to learn something - which is a good outcome in of itself.

 

I'll post anything interesting to others.

Marantz PMD340 has very basic power supply + top quality mech and has rca, xlr and toslink digital out. Where are they and how much?

IF you have access to a step down transformer, you could measure the DC rail voltage feeding various parts of the circuit. Something like this might simply be +5v but it depends on a lot.

You could then completely bypass the unit's power circuitry, and either a) solder in a ready made linear power supply, or b) build your own and solder it in.

Probably more hassle than it's worth....
