Default Thank you Azmi and Nico Ras

I will inform the layout designer about it.

regards,

Carlos

It is solid copper cut from a sheet 3mm wide x 1.6 mm thick. However some designers would recommend running a star positive and negative supply directly from the capacitors, which I would think is still better, but it does not look very nice.

It is simple to apply. I smeared solder paste and then heat it with a small butane gas torch.

Default Voltage drop on power trace

Nico,
I have never really given much thought to power trace voltage drop. You definately have something here with a very high output amp. Feeding the power trace in the middle would also be helpful. I will give this some consideration when I start constructing the heatsink and chassis layout
When being fanatical about amplifier projects this is just another nice thing to add in. In differentiation amongst the outputs will show up somewhere.

Thanks Tad

Default Not only voltage drop..short circuit may destroy the track

If you make the way he told us...track will survive do 30 amperes or more.

regards,

Carlos

Hi Carlos,

in this particular amp I have to pass currents of 56 and more amperes. This can make a hugh difference in powewr dissipation/ It was only a thought. Have you check what is the peak current that you may pass, assuming it is an instantanuous current. Perhaps 10 amps, very probably more?

I think it is necessary to divorce the rms current from the peak or music current. This is the erengy that the capacitors can instantanuously dump into the load, not what the transformer is capable of.

I had an interesting experience when testing this amp looking for speakers. I asked the salesman what is the most powerful speakers he has for full power testing and he recommended some Rockford fosgates.

I said to him, this is a pretty powerful beast and he confirmed that there is no better speaker available for the job.

I asked him to connect some wires to it and insert it into the ac mains wall outlet - he looked at me as if I was mad. But I told him if they play a good 50Hz note for some time I will take two.

He refused my test and I told him, his speakers will not do the job.
