Component Placement Revisted

[skypn]

As per my previous post, are there any issues with the component placement for this simple LM 386 amp?





Or that matter, any issues at all?
TIA

Nice and tidy. You have room for a reverse polarity diode off the the V pad and a pulldown resistor at the output (don't know the application here so maybe they aren't needed). Is there an reason for the large output cap?

[skypn]

The application is just a little amp with a recycled tv speaker to test circuits without having to whip out my amp at first. The large cap is because that is what the schematic called for, and it works nice on the bread board. Do you have a different value to suggest?

Ahh, no I say go with the schematic you are using. It's just that 1000uF is going to be pretty tall, so if this were something you wanted to box up at some point, you might consider adjusting the layout so the cap can lay flat across the bottom of the PCB.

The box I'm putting it in will also house the speaker, so plenty of real estate . Its not a pedal, just a test speaker.
Thank you for your input, I'll mill the board on my CNC this afternoon.

Is it worth having a ground plane?  Or is that too much trouble if you're milling your own?

For something this small, I don't think it's necessary.
