[QUOTE="Contrabass, post: 34815, member: 602"] I think Gertus was trying to get to 470uF so I think he was correct in paralleling the caps. But that is of little relevance as the psu actually uses 3x 47uF and not 470uF. methinks quite low values for smoothing caps but Gertus tells me that the resistors in the psu design aid the smoothing. Who am I to argue with the learned lad ? Here is the (modified) Alembic preamp power supply schematic. Basically, the isolated secondary 220VAC is rectified by the bridge rectifier and smoothed via the caps and resistors. I am sure this makes sense to the valve-ites out there ;) [/QUOTE]
