Configuration power supply

[Darry]

Hello,

Can you say to me, among these 3 configurations (A, B or C), which is the best, the most interesting for the power supply of a preamplifier ?

Thank you for your answer

I'd vote for B cause it makes highest RC constant for equal R. But I would use much smaller caps and go regulated.

It seems to me to have read, I do not know any more on which forum, than John Curl with CTC Builders use the B configuration.

Hello,

I would like to recover these comments of John Curl.
What forum ?

Thanks
