Hello Graham,
again long time ago since our last conversation.
Hope that everything is smooth with you and your family ?

Iam still happy with your/my revalation and my great sounding laser turntable(upgrated again two years before..).

Sorry to ask you as a analogue guru, maybe to support me here with streaming….

Your PS1 have a DC output of 24 Volt,but how many amps ?
And which transformer is inside and what about the wring ?

Reason iam asking here that i need a 12V DC linear power supply with at least 3,0 ampere.
Is there any way to make that from one or two ? pieces of  PS1 ?
The plan is to replace another linear power supply from a networkplayer.

Whats you thought on that ?
When you see no real possibile or you dont like that idea, maybe you have recommandations for another high quality manufacturer ?

thanks Robert

Hi Robert, I was about to reply to your email asking the same question but things have been a tad busy.

The PSU1 will not be able to give you 3 amps because the transformer is only a 12VA rating, and if we had one made suitable for 12V DC use it would only do 1A. It would also get very hot which would soften the case.

I am working on a 5V 3A power supply and it may be possible to uprate the transformer to give the required voltage and current for what you're after.

12V at a constant 3 amps is a constant 36 watts. Which begs the question, what are you wanting to power?

That none should be able to buy or sell without a smartphone and the knowledge in how to use apps
