AIYIMA A07 TPA3255 Tear Down

[gasolin75]

30V .5 A would seem way to small but don't forget the 10:1 peak to average ratio of music

That's one reason i wanna have something bigger, i don't think just because i have an 10a power adapter that i would use more than currrent if my power adapter was 32v 6a

to get a tube sound from this amplifier use an unregulated 32V adapter 30V .5 A would seem way to small but don't forget the 10:1 peak to average ratio of music I use a Jameco clarity can be improved by replacing the 6V reference for the opamps with a 5.6V low noise zener and using OPA32 TI opamps

Unregulated 32v from a switching supply?

What I wonder is how no one has tried using a linear DC supply, as 32v 5A wouldn't be that large or expensive.

Has anyone modified the A07 following the TI datasheet, that seems to show how to bridge the TPA3255?
