ripple values in B+ supply

Antonio Tucci · 2nd September 2006, 09:11 PM

In a 2-stage 2A3 amplifier (6C45P-2A3) which should be the values of ripple in the B+ supply of the first and second stage ?

About 70mV max. for the output stage (30 or less being very good), 10mV for the input stage (3 or less being very good), other people might have other standards...

Edit: that's my baseline for two-stage single-ended IDHT, dunno what's the drill with DHTs.

basically run a bunch of sims in psudii with real-world chokes and caps etc. and build the best one you can afford/have room for.
