slow ramp 48v phantom

[hitchhiker]

Thanks Charlie for sharing this circuit ,I know I'll be using it.

For a learner like myself there is much to be learned by the debate over
a basic circuit. This place is great!

Rafa , I will also buy a few of these boards if you make them.

cheers,
Lance

you could add a 10 ohm 1/4 watt between the bridge and cap. this would provide surge protection for the diodes and also act as a fuse in the event of a catastrophic failure somewhere.

can I use a trimpot for R1?

Rafa! So sorry I had not noticed your question earlier...

Why do you want to use a trim pot for R1?
