AudioPro Allroom One: 72 volt battery hack!

[@beauchampy]

Do you repair these? I have one here in the UK which only gets a hiss on line in, and the airplay mode only drives the tweeters.

Hello I saw a video of you repairing a plate amp for a speaker. I was wondering if you would be able to repair my plate amp that is in my Focal Solo6 be speaker.

The joy of using DC, well, sort of, still a pain in the bum to get multiple voltages out of one supply, but that's what these SMPS devices do anyway... :P

[@bhasselgren]

Did you say that you measured 30+5 DC volts on the cable to the "motherboard"? The reason why I ask is that I have a broken PSU, I think, well the wifi, display, etc. is working but no sound (no matter the input) so I think that part of the PSU is broken and wanna try to replace it with an external PSU.

[@FFcossag]

I think the power amp runs off of a single 30 V rail, but I might not remember correctly.

....Nice! im gonna go make a cuppa T then watch this, while dunking chocolate hobnobs, Cheers FF

[@FFcossag]

Hehe, cheers!

Pretty cool, I forgot about the DC in on switch mode P S

[@gamerpaddy]

i would have used one of those 120VDC dc-dc boost converters, this way im more flexible at the input voltage range and what batteries i can use.

[@FFcossag]

I considered something like that, but I didn't want to A) add more conversion steps B) deal with the EMC or C) have to wait until fall to have it arrive. ;)

[@johncoops6897]

I would have just run the 60-70V DC straight to "secondary" of the SMPS, bypassing the mains side of the converter completely.

[@FFcossag]

That would have broken everything.

Love the Nokia

Alas, it's not very loveable. The new 3310 just feels like a generic cheap, laggy budget phone :(
