[Amps] 2500 uF at 450V DC for $10.00 each

[Mark Hill]

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.
