Hi Drow,
Could you do two layouts. Make one channel using your proposed scheme, then the other using the scheme in #8. This will provide some pretty good experimentation.

This amplifier will change what you know about power amplifiers 😉
This is the first edition of the schematic that will go with the PCBs.
What connectors would be suitable for the power supply and output on the PCB ? Or is soldered wire preferable ?

perfectmate for a good power supply...
what is the purpose of a good power supply when you have a bottleneck at the amp.pcb...😡not only voltage will sag but will create noise😀
I have put a bridge in here, but still it has a two gnd returns.I have manage to silence the symef with only one gnd return and sure it will not be a problem in here.enclosed in zip is the top and bottom of the pcb. so you could peek.

spend in speaker....
I have a vintage receiver only 15 watts per channel and my sound system can actually go down really low.instead of buying expensive capacitors I would invest in a good speaker.
I have read also that linear regulated supply and smps are a bad choice for a highend amplifier.the only thing that it is good is manufacturers can bought semi conductor devices at a very cheap price when bought at large quantity compared to big transfo. and huge capacitor.besides it operates at high speed this creates rf signals and you have to put sheilds on this and will require a space in enclosure.
and smps requires feedback and should be fast enough than the amplifier..and reliabilty not so good.
and during transient signals raw power supply is the best.🙂
no wonder how exotic my computer power supply is still cheaper...

Hi Harrison, the schematic in #1 is very much that of KRELL KSA50 of the early eighties with some minor modifications. The dual complimentary symmetry has a characteristic of sounding more powerful that it really is. In other words a 50w amp sounds much louder than expected. The MJL15002/3 are better suited I think than the 2SC5200
It is a very popular amp and produces very good results.

Here is what I am cooking, If you see something that you no like or something you got better idea please scream😀

my work is finished...
I believed that I have reach the peak for this amp.I have done some research and making sure that I dont throw punches on air....
theres a lot of advantages offered by a dual and multi-layer pcb and believed this will solved bottleneck and makes the amp. be distinguished from the rest.😎😎😎

Hi Joel,
I agree with multilayer because you have more chance to make conductors at right angles and avoid induced junk when sensitive and power tracks lie in parallel with each other..

Nico,
That is still playing with me. I have not manged to have a casing for it.
But when I feel like listening to it, than I will connect the PSU and speakers to sit down together 🙂)))
Sure it sounds very good and powerfull.
Kind regards,
Raj.

it will take time...
I get the idea on RNMarsh pcb if his attachments were not there I could not imagine how to implement it.

you know what matters....
I like cars what really sets them apart is which one is the fastest😀😀😀
I dont claim that I invented this I just did my homework and solved the puzzle those that are left behind be a sport...😉
