  • Behringer p2502 poweramp module

    Got a Behringer Pa with p2502 poweramp module can't quite figure out how to insert the pdf into the forum so I have a screenshot of the section I have a question about.

    There are some burst caps c31 c32 c36 c37. 220uf 50v

    Can I use 470uf 50 and still be ok?

    soldering stuff that's broken, breaking stuff that works, Yeah!

    Thatīs a voltage multiplier to get +48V phantom for the active microphones.
    Guess you might double capacitance but why?n 220uF x 50V is a very common easy to get value, so just use bthem.

    You will NOT improve ripple or whatever since actual 48V are regulated by T17 and associated 47V Zener D53
