tassie tiger Posted July 28, 2014 Share Posted July 28, 2014 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. Link to comment Share on other sites More sharing options...
ThirdDrawerDown Posted July 28, 2014 Share Posted July 28, 2014 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.

GregWormald Posted July 28, 2014 Share Posted July 28, 2014 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. Greg Link to comment Share on other sites More sharing options...
tassie tiger Posted July 28, 2014 Author Share Posted July 28, 2014 OK, thanks to both of you for your replies. I was naturally hoping for better news, but resigned to finding an overpriced 240V 50Hz model from euro-zone or local-zone. Cheers, J Link to comment Share on other sites More sharing options...

I'd suggest it's not worth it. Greg 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. Link to comment Share on other sites More sharing options...
PCOWandre Posted July 29, 2014 Share Posted July 29, 2014 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. Link to comment Share on other sites More sharing options...
tassie tiger Posted July 29, 2014 Author Share Posted July 29, 2014 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. Link to comment Share on other sites More sharing options...
Guest rondine Posted July 29, 2014 Share Posted July 29, 2014 Marantz PMD340 has very basic power supply + top quality mech and has rca, xlr and toslink digital out. Where are they and how much? ron Link to comment Share on other sites More sharing options...

Mondegreen Posted August 7, 2014 Share Posted August 7, 2014 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....
