Rotel RCD-9658X, convert from 230V to 120V?
 
I am looking at this Rotel player, wondering if it would make a good unit for upgrading/mods, but first I would need to convert the power supply from 230V 50Hz to NA standard 120V / 60 Hz. Is this a major issue?
Any opinions on this unit, or the power supply mod? Any schematics? Thanks.

Most of Rotels has main voltage selector switch on rear panel, under protective cover. You can see it.
Or, go to Rotel manuals archive and take a user manual. Check specifications at end, about power requirement. If more than one voltage listed, this device must have the selector switch.
Or, ask from seller.

If a voltage selector is not present, you have an easy option to solve your problem. The power supply transformer has taps to adapt to 120, 220 and 240 V AC mains. You have to desolder the wire from the currently used tap, and solder it to the 120 V tap.

Thanks, I didn't realize they had manuals online. The manual says 120V 60Hz or 230V 50Hz "depending on destination", and there doesn't appear to be a selector in the picture of it. The seller says it was bought in Europe, although the back states "certified to Canadian Electrical Code".
Is it possible the selector is hidden inside? If not, is it a big deal to convert it to 120V?

Thanks

Here is main input of RCD-971. the picture only I have:

No selector switch, but the board under plastic cover has wire mounting pins with clear marking how should be soldered or for inspection.
Very easy.
Don't plug power cord to outlet before opening!!!.

Thanks! I can handle that I think... I'll see if I can nab it now.

Ok, so I'm a bit slow in replying... :-p

I picked up this player based on the advice given, and sure enough, swapping from 220 to 110 input was very simple. I've been listening to it ever since, and quite like the sound. My unit is missing two of the control buttons - any chance someone has a parts unit? It appears other Rotel models of similar vintage may use the same buttons?

RCD-965BX service manual is listed in this thread:

Also some valuable info is given on repairing/replacing parts.

I recently (2 months ago) still sourced a plastic button grid/inlay whatever you call it for a 955 from my local distributor. I think the layout of this grid remained for a while (855/865/955/945/965/970/975 I think are all same spacing etc just the newer ones 9 series have some lines moulded in and are curved.)

Thanks, I've just sent an email to Rotel service asking about a new button panel, along with the service manual for the RCD-965BX. The RCD-855 manual appears very close, but it never hurts to ask them - if I get it, I will post it here...
