Keantoken's CFP cap multiplier

[tinitus]

I have additional power supply lytic caps
one at power in, and one at power out
mine are all 470uf/35V..and also the '820uf'

tinitus, thank for your info.

if you make room for 'optional' bridge diodes, and a few more lytic caps, it would be a complete power supply for preamp etc, with nothing else needed
and remember the LED/bleeder resistor
but only ofcourse only 'optional', in case you want a bigger lytic power bank

I would suggest at least a small input lytic.

Tinitus, Kean, thank you for suggestion
here is my layout

In+ text is missing. Everything looks okay to me.

Another small mistake is that "Ground Input" (at left center, next to the leftmost mounting hole) is labeled In+.

Nice job on the star ground! The 470uF input filter caps are placed at the far end of the raw unregulated In+ and In- PCBtracks, so ((the capacitor's ripple current) x Ztrack) noise is seen by the active circuits. On the other hand, it is a ripple filter after all; it's designed to work well in the face of ripple on raw unregulated In+ and In-.

BTW the TO-92 packaged transistors don't have partnumber labels.

Thank you everyone,
i'll build mine with this layout.
