Dear Forum Members,
I have a question about a current limitation in a power supply for a Tube preamplifier output 215 Volt.
The question is Does this work if you accidentally create a short circuit?.
Here is the diagram of 2 different power supplies, the first one broke due to a measurement error, of which it is not entirely clear what went wrong.
The second diagram is of a tube preamplifier from Audio and Technology from a long time ago, I personally think the current limitation of Audio and Technology looks better.
When I simulate in Tina Software, the current limitations of both seem to work, but as I wrote before, the power supply board of the first diagram broke after a short circuit.
What is the opinion of this Forum about the two power supply diagrams?.
Greetings,
Pim
Just connect them in series:
0V on the first one to Neutral, 120V on that to 0V on the second one; the "120V" terminal on the second winding is the 230/240V input.

Some things seem very easy, but before it is really understood, sometimes you need a drawing, the question remains, did I do it so well?.View attachment 148758
Dear Forum Members,I came across this Shunt regulator, and am curious about the reactions to this regulator.
What would this do on a Tube preamplifier.
In Tina Software it seems that this regulator is short-circuit fixed, but that is still the question.
The question remains is this a stable circuit?.
