Increase L in pi network

Posted by Sidewinder on September 22, 2017 at 00:15:20:
Hi,
My stereo 2a3 se amp has a 5U4- 47uf-15H-47uf power supply, putting out 320 volts of B+ . What would happen if I increase L to 25H? Would B+ voltage increase or decrease, but more importantly would it change the sonics of the amp for the better or worse? Another question, would It matter if the replacement choke was designed for a L input supply? Any insights would be appreciated.
Regards,
David
