Default need advice for my aleph 3 new idea ?

hi

My aleph 3 is in good progress

my overbuild power supply is:

68000uF+1.2mH+68000uF+1.2mH+68000uF

ripple with 4A test:
500mV on C1
50mV on C2
5mV on C3

my new idea easy to do just transfer 2 wire for bigger
ripple but maybe normal ripple but is it a good idea
for better crosstalk and stereo image ?? :-)

thanks

Hi,

maybe your post isnīt that clear? Do you want to make a stereo amp with just one transformer, one bridge and one C1 and after that separate them with two Līs and two C2?

This should work gine although I would choose the chokes a bit bigger (1.8-2,2mH).

Hi,

personally I always prefer double mono power supplies so I would opt for the second sollution where thereīs some kind of separation between channels. I never tried a stereo supply on an Aleph though, only on class AB amps.
