50vac to 48vdc phantom rectifier/regulator schematic? Also 12vac to 12vdc?

Hey folks.

I've looked everywhere and can't find the answer. Forgive me if it's hiding in plain sight.

For my next 2-channel tube preamp build, I want to try using a single toroidal transformer with 250v (B+), 50v (phantom), and 12v (heaters) secondaries. I have a few questions.

Does anyone have a schematic of a rectifier/regulator circuit for 50vac to 48vdc?

Does anyone have a schematic of a rectifier/regulator circuit for 12vac to 12vdc? (I would prefer to run the heaters with DC.)

That is all. Thanks in advance.

Here is the transformer I hope to use: http://collectivecases.com/?product=psu-transformer-szl-54

Check out the power folder under the DIY tab of my website:

Ian, thank you so much. That is perfect for the 48v.

Do you have a similar schematic for 12vac to 12vdc for heaters?

Go to the Lunchbox folder in the DIY tab and select the PSU folder. There is a pdf document there that describes all the various lunchbox power supply PCBs which provide HT, phantom and heater power.

I should buy you lunch. Thanks again!
