Plugged this in out of curiosity. Probably a dumb move. But it works. Audio output is fine.
How???
Is it the 12V output is “max” and the OT is regulating it to 6V?
My understanding is the 3A would be the “max”, not voltage.
@darenager to the rescue…
The internal regulator in the OT will bring the voltage down but depending on the rating of the part, might be better avoided as it could fail.
To be on safe side have a look at OT internals and see what spec the regulator is, some have very wide input voltage range others don’t.

There is no way that the OT can influence what’s coming out of the battery pack. My guess is that the OT is built to regulate it down internally for safety measures.

That’s my understanding as well.
I wonder how safe it is…
Does anyone know this spec off hand?
@Augenadler perhaps? Who has built in a 12v to 6v regulator in his own OT
is the mk1 6v? the mk2 is 12vdc
Depends on the spec of the voltage regulator E uses and the circuitry they have.
Test it at 48V. (No don’t do that!)

Yep. We wouldn’t be here if it weren’t.
same as MD MK2 / MM MK2
hmm, seems like an odd change for them to make…
perhaps they switch later mk1 to 12v? so then just labelled it up on the mk2
(perhaps moved to using same regulator board as other elektron models?)
I see what you are getting at.
This is a late manufactured OT MK1, produced after the 12V A4 MK1 and Rytm MK1s were produced.
@Olle ?
yeah, we should be very careful here if this is the case… as might make an earlier mk1 go pop

Good point, de-listing the thread from public view now that I’ve tagged the expert parties
great link!
From that post, the power board:
P1173 183NL is the power inductor. is that what I should be looking at ?
Here is the data sheet for that part:
It’s rated for 4A DC
(I am not terribly electronically savvy beyond my knowledge of the difference between amps/watts/volts… ac vs dc…)
The power inductor is just part of a DC-DC circuitry.
The 12.24 are physical dimensions (max, because they may vary a bit).

of course.
Well my ignorance is showing. I’m going to have to rely on people with more experience than I.
