How much capacitance in a power supply

TugaTweaker · 29th January 2006, 03:51 PM

Who can help me with theory ?

In a 440v SS power supply with a 220+220UF 500v Black Gate two+two series of 600v SiC schottkys rectifiers plus two paralelled 15 H chokes to ensure more miliamps , which was working well , without no listenable hum or other noises , I finnaly added an old ITALCOND 2200uf/450v lityc can . To my surprise the whole
TT22(=KT88) SE amp gained a new life which surprised me a lot .

The answer : Will a brand new 6800uf/450v EPCOS increase the
more capacitance good effect , or should i be aware not damaging the valves with all this miliamps ?

Thanks in advance

There is always a point of diminishing returns. If your rectifiers are up to the challenge of initial turn-on currents, try it and see if you like it.

It is unlikely that too much capacitance in the power supply will actually damage the amplifier section of almost any amplifier.

Thanks Stocker , you understood me nevertheless .
