Ah ok, very helpful, thanks a lot!
Never do this at 1 a.m. prioritising checking the firmware over voltage@AnakChan, what were you thinking?! . Hope you're well back home besides that little hiccup!
If you have a whole bunch of 110V gear, it might be worth getting a proper step down transformer instead of replacing the devices. If so, you could just test the SU-1 with that transformer.Folks I've done a -very- silly thing. Moving back from Japan to Perth, I didn't check the Singxer SU-1 properly and plugged a 110V device into a 240V source.
Back fro, the electronic store. Bought a fuse and replaced it but sadly the SU-1 is still dead. I guess the PSU or Talema transformer must have blown. Now to decide to talk to ShenzenAudio on parts, or look at one of those PSU upgrades (all this in assumption that it's only the PSU that's blown!).
You evil sinister man !!or bite the bullet and go with the su-6 (evil grin), https://www.head-fi.org/threads/singxer-su-6.902272/
We are in the same town . Yes I found that switch only after I blew up the internals. I've replaced the fuse with a new one from Altronics and it still doesn't power on so either the Talema, caps or more may have blown.@AnakChan - the Singxer should have a mains voltage selector inside it (see below) -
As the supply uses a linear regulator, I would think (hope) it would be OK as long as it was not on for too long. The regulator would have to deal with a higher input voltage and so it would run hotter. The other risk would be the first capacitors too, as they may not be rated for double the voltage. I would open yours up, change the voltage, put in a new fuse and then connect it back up to the mains (but nothing else).
If you're in Perth Western Australia (and not Scotland), we're in the same town, so I can give you a hand if needed (send me a PM).
PS another thing you could do is buy a Ghent audio or Kitsune hifi singxer SU1 5V kit. Bypasses the PSU and then you can use any 5V power source directly.We are in the same town . Yes I found that switch only after I blew up the internals. I've replaced the fuse with a new one from Altronics and it still doesn't power on so either the Talema, caps or more may have blown.
I didn't want to open it up prior 'cos I didn't want to break the warranty seal (and the external said 110V/230V, and the fuse was 250V) - so tried my luck.
P.S. Since we're in teh same town, we should catch up . I used to organise Head-Fi meets in Perth whenever I came back into town. Now that I've moved back, would love to organise another Perth Head-Fi meet!
Fuse protects against over current (short circuit) not over voltage.Folks I've done a -very- silly thing. Moving back from Japan to Perth, I didn't check the Singxer SU-1 properly and plugged a 110V device into a 240V source. Whilst it has a fuse, it's a 250V fuse. Does anyone who's familiar the SU-1 PSU circuitry if there's any protection that'll cut off to protect itself or have I blown the PSU? No I did not open it up to flip the switch before powering it on - I didn't want to break the warranty seal and the back of the socket did say 110V/230V (and the fuse was 250V).
The fuse did blow however being rated 250V, however I think that is just for a protection overload for the -max- the SU-1 can handle aside (irrespective of the 110/230V switch). So my only hope now is that the PSU has some other kind of protection mechanism. Anyone familiar with it?
