looking too buy a National. it says 100v only... it will work here in north america? 0n 110 120? i have heard 110 220, but never 100.....
I beg to differ....Reli said:It's OK unless you insist on cranking it up and/or using it often.
That also worksAE_Stereo said:Just would like to know what is the general opinion about using AC to DC converter to feed 12V DC (or the specified voltage) instead of going for an AC converter.
I do that for my non-standard voltage boxes.
Everyone is entitled to their own opinion last time I checked.Kenpat said:& much safer!
Before we forget, let's all say to :superduper: for having the patience to answer this question yet again. When it comes to safety (Scott) we can never be too sure when using boxes from overseas (Scott) and should always exercise proper caution (Scott.)
Safety first! (Scotty!)
Now I'll get right back to work on this chip I blew up testing under power...
Yes. I feel it is safer. Hence whenever I get a new box in unknown condition, I switch it on the very first time with DC power supply. Apart from a shock hazard, it may also incur a lesser damage if there is a short circuit inside.Kenpat said:& much safer!
That is correct!AE_Stereo said:Yes. I feel it is safer. Hence whenever I get a new box in unknown condition, I switch it on the very first time with DC power supply. Apart from a shock hazard, it may also incur a lesser damage if there is a short circuit inside. While using DC supply, make sure that the Polarity (+-) of the pins is matching with the box's pin configuration. I have seen many Japanese boxes with negative on the center pin and positive on the outer one, especially the National Panasonics.
Me too. If you do this, be mindful of the polarity of the pin; some are positive while others are negative.AE_Stereo said:Just would like to know what is the general opinion about using AC to DC converter to feed 12V DC (or the specified voltage) instead of going for an AC converter.

Hell, I've never owned a box that can even hit 40% without serious distortion.BoomboxLover48 said:Also I won't play a Boombox more than 60% of its volume.
