Folks,
I have 16 x 2200 uF, 400 V electrolytics in series in the supply for my new
project PA and share Conrad's thoughts on the stored energy
issue. Sometimes the components to hand are not ideal for the job. I will
let you know what the bang sounds like when I get one!
Of course, the other side of the coin is the typical 20 and a bit uF of
smoothing provided in several US-built amplifiers. Not enough for us 50 Hz
types, even with an aluminium plate under the capacitor bank!
Regards.
Mark.
