My Rytm 'Flashes' in the dark occasionally, without any power!

This is a generic transformer ac to dc power supply diagram.

With this circuit a smaller ac current at the input will slowly build the charge across the capacitor.

But the rytm has a switching power supply, without the transformer.
But the rectifier with the capacitor look like a possible cause if there is leakage current flowing in.

the one i have is sealed tight.

A transformer would be bigger then the rytms power supply. The supply is pretty small and flat so i’m pretty sure it’s a switching supply.

My Rytm streaked a party the other day, buck naked, no pl-2…

I think of significance here is that this requires a low current leakage coming in from the surge protector, which i would not have expected, though possible,

Sure. I didn’t dispute this.

Switching power supplies are usually more expensive and can have the problem of high frequency interference.

I think they are usually cheaper. And they do ideed have noise problems.

I actually bought a kit for a linear power supply (so the non-switching, tranformer type) the other day. It costed 100 euro and came with a separate heavy ‘brick’ which houses the transformer.
I think all the (nessesary) copper in the transformer is what makes it so expensive.

About leakage, it’s possible the surge protection circuitry is active and leaking somethig to the device side.

You’re right that a switching supply can contain a small transformer but i’m not sure the same ‘charge building’ theory applies because there is an active switching element in the path.

I don’t think it could be the ‘stored charge’ thing because that would work only once and then the cap would have lost its charge.

So it definitely looks like some leakage in some way.

great thread btw

This got me thinking, you know of a forum that talks about this sort of stuff? D love to lurk on such a board, as this sort of stuff interests me yet I am completely clueless about it…

Shhhhhh…

I replaced the Psupply of my elektron md and eventide space with linear PSupply …no more sys crashes

Always disconnect your machines at night… they might come alive and kill you in your sleep!

Check out the movie ‘LFO’

Its a fun movie! Very unique.

I wonder how good Elektron equipment is to resisting high frequency audio interference?

Well, i don’t actually see any negative effects on the rytm, so i suppose it’s not a problem, at least in that case.

Hello, let me join this club of (attention seeking) owners of attention seeking RYTMs. Are your RYTMs still well and alive? Did you take any precautions to prevent this from happening?
