As Patrick said - there is more than one way to skin a cat. As I reiterated
in the Turbo, more current is better as long as you can take the dissipation.
At the same time, I respond to people who complain that 25 watts or
whatever is not enough.
Graund plane...
If you can put one on it why not but not rely needed immunity to ambient noise is realy good.
I did not as for home brew it complicate things in my case. (I can be realy dangerous whit paint brush or other precision things such as lining up wall paper)
And if you buy board stay away from farnell old stuff with baad photoresist in a couple of batches to many

Ground plane 2
NP does not use ground plane, nor do the majority of really good amplifier designers for the simple reason that they are not needed.
A good layout does not need it, no need to complicate things ~
We are just working on power stage not low level signal input stage ( preamplifier )

Yea I know don't have one but if one feels like it and can pull it off it shuld not be forbiden to stick one on it.
so what you recon is good lay out then?
Show us same porn

I was reviewing the F5T pdf papa provided and examining the differences between the various schematic versions when I found what I think is an error. On what he calls the original schematic (with P3 added), he has the P1 wiper tied to the positive rail, but P2's wiper is tied to the drain of Q2 and not the negative rail as shown in the V1 and subsequent drawings. Anyone else care to confirm whether this is indeed an error, or an indication that I'm CS and not EE?
Taking F5 PCB that drawn by Peter Daniel as reference, the R3 and R4 is using a 1/4watts size as well. Correct me if i am wrong.
I don't think miliampere would cause problems?For Input and decoupling ground, can you elaborate more about it?
Let say i have a common ground at point "A" which is near PSU, should I route the signal G and Decoupling G direct to there without joining them on the amplifier board? (star ground)
But from What I read on the F5 layout that drawn by PD, the signal ground was joined together on amplifier PCB.

I plan to mount the diode arrays and the output devices on a 'heat spreader' (a piece of 40mm x 10mm x 300mm aluminium bar) which will then be mounted onto the heatsink.
Do the diode arrays need heatsinking? I'm not sure, so I'm planning on doing it anyway.
Incidently, with regards to the Turbo power supply; what are the diode arrays? More MUR3020's?
