aleph 1.7 power supply

[jarthel]

having seem various tube voltage regulators, I have a feeling that the power supply for the Aleph 1.7 preamp is a series voltage regulator. Is this correct?

What should be the voltage going to the preamp circuit?

Thank you.

I presume that NP knows that this information is publicly available, and hence does not object.


Jarthel have a look at the manual...

Although I have not built one, it would seem as if the supply to the active circuit is 60V from the series regulator.

thank you. I am guessing the string of zeners acts as reference for the series regulator chip?

Actually it's a FET not a chip, but yes, they do as you said.

Jarthel,

Do both yourself and us a favour. Go read the Zen articles, they ansver 99% of the questions you're asking, and the last 1% you should be able to figure by yourself after reading those articles.

I thought zen where power amps. And I was talking about preamps.

As I said, if you think I've done something wrong, report it to the mods.

Me likey Cello schematic much nicer to look at, still not finished though.

Go and read those articles as Magura says they also include preamps plus the benefit of the author which is no less than Nelson Pass instead of hearing bits an pieces from all of us.

They are free for you to download, what more could you ask?

Ignoring bad behavior is never a good policy. Try raising children sometime and see how far that attitude gets you.
