Mini A Power Supply

[harry303]

Hello,

I want to build the Mini A,

but I don't know how to build the power supply.


Transformator should be 300Va 12V

and caps 1F for each channel.

How do build the rest of the power supply

when running at 230V 50Hz ?

I was just about to suggest the same for a starter.
You can get by without the coil depending a bit on your speakers.
Quite a few built it without the coil but a bit more capacitance.
(You should of course include a fuse on the primary side)

Do a search here in the forums and you´ll find loads of different setups.
That should also give you an idea:

I would go with at least a 15 volt transformer. Build a C-R-C to get 17.5 volt rails. Anything over 50000 uf per rail total should do the job.

Big THxs, that was exactly that what I'm searching for
