Just learning PCB layout, this is the version I worked on, it doesn't look too pretty and cannot make it any smaller. Cannot find the correct lbr for FQP3P30 so just use any small mosfet for the layout.

Turn Q1 round 180 degrees, and move the MOSFET pins up by 5mm or so.
You will then be very close to the Vero layout.

Nice work and a good start - what software are you using? I'm glad you are using 2 sided layout functionality. 50mm x 50mm 2 sided PCBs cost the same as 1 sided: $10 for 10. 🙂
Nice layout!
You could put the 2SK170/J74 back to back so you could thermo couple them easily
Maybe we could ask Alex_mm to make a layout for us?
Thanks

I am using Eagle7.2 . A vero pcb will cost $20hkd so better off to do a PCB instead. I put the jfet side by side because I got a few pairs of those nice heat sink from Patrick's friend few years back and want to use them.
Is a HK$ not similar to USD? Here are pretty inexpensive verobiards 4x6cm that I use. 10 for $6 shipping included.

Patrick, what exactly about Prasi's layout makes it not up to your "high bandwidth" layout standards?

1US$ = 7.8HK$, a 7 x 5 cm double sided veroboard cost about 2.5US$ here from local stores ( same veroboard as your reference link), the PCB cost about 10US$ for 10+1 boards with shipping. Double layered PCB is better to work with than double side veroboard IMO.
P.S. I made these PCB for my own learning purpose, not selling!

Your tracks to the MOSFETs are too long.
There is no real need to put the MOSFETs far apart since they do not dissipate > 4W each.
Which is nothing for a TO220.
And you want a thick wire, like 1~1.5mm to connect Output Gnd to PSU Gnd.

It does look a lot tighter now. Can you bring it up to 50mm an add a couple 1000uF rail caps?
Thanks,

Yeah Prasi...you heard the man. Make it larger and get those massive 1000uF caps on there.😛
Might as well stuff as many components on there that you possibly can on that 5mm x 5mm board. More for the dollar, right "x"?
That's cool - thanks for making what we have so far. Can you please post the Gerbers for last one?
