Best 24V PSU for 33609?

[Golgoth]

Hi,

I need to replace the internal PSU of my 33609 type compressor (83046).
I don't have time to build one myself and would rather buy a great 24V PSU I could install in the box.

Do you guys know of a great PSU for my needs?

Thanks!
G

Depends on what kind of PSU that you want. Linear or SMPS. Since I don't use linear anymore, my recommendation for SMPS is Mean Well EPS-XXX-24 or RPS-XXX-24 where XXX is the wattage: 15, 25, 35, 45, 65, 120 but unfortunately, they're hard to get these days. Aside from MW, I also use Delta Electronics SMPS.

Thanks for the recommendations!

Had great experiences with Mean Well products in the past but it's been a few years and I feel pretty out of touch with brands and references. SMPS would be perfectly fine I believe! I'll check the references you mentioned!

Regarding wattage, what do you think would be optimal for a 33609 compressor?

RFS series I have not used personally, but the EPS series (I think it's the same, RFS is just certified for medical use) I have. I suppose if you take out the main power transformer, you can make space in the enclosure for the Mean Well?

33609 internal power supply board also contain a couple of relays switching circuit for the audio signal. Make sure you ONLY remove the power supply components (see page 23)

EDIT: oops sorry, I thought you're replacing the internal power supply of a real Neve 33609 unit

It is a 83046 unit that was fitted with a custom power supply 30 years ago and that has seen better days.. Basically a console version of the original 33609 that used to get it's power from the desk.



I think I have all the room I need to fit a Mean Well! Not sure about which wattage to choose.

If that's a 7824 regulator in a TO-3 can, then the current draw must be less than 1A.
Go with EPS-25-24 / RFS-25-24.

Chances are your existing PT is not the root of your issue.
You might go the linear route and consider one of those cheap PSU boards from Audiophonics

That works too.

I'm pretty sure Volker has a 24V linear PSU on his white market page as well.
