Thanks for the graph, ACD!
So, by the graph i relize that my rectifier, 35A, can be pushed to deliver some 31 amps without any trouble on 40C summer temp
Ok, mounted a small heatsink ofcourse
Other thing about this i want to ask. I have made the amplifier 2x40w runing 6 ohm speaker. Transformer is 2x20V with 4 Amps, for stereo. Rectifier is 35A and does not have heatsink. Is this safe for rectifier? Only 4 amps and no heatsink?

it's easier to drill one hole and fit one screw than to write two posts
Hi,
since only 1pair of diodes conduct at a time then the voltage drop is 1.4V.
Peak charging currents are quite high, but assuming an average charging current of 2A, gives an average dissipation of under 3W.
That 3W is easily dissipated on just about any metal plate and allows amplifier consumption of around 200W.
No worries.
