You may want to check the schematic of all the parts before the big capacitors first. The inrush current will be quite high when charging the bigger caps. Make sure those other parts can also handle the currrent too. Other experienced forum members may give you more detailed suggestions I hope.
+-44mF is quite a lot of charging at start up.
Is this the only cap bank off the transformer and rectifier?
How about developing a slow start circuit, or just copy one off another thread. Have a look at Peranders version or go to the ESP site.
Thanks for the replies guys
I think I will stick with 6800µf
At first I wanted to put 22000µf cause i thought I would lower ESR
and the 22000µf Thel elkos are about the same dimensions to the original 6800µf in my amp.
But since I have just purchase RIFA 6800µf with quite low ESR, I think i will do with the safe replacement. Thank You
