Default BPA200 PCB design

Hi Guys.

My name is Narong from Thailand. I'm very interesting in BPA200 based on AN-1192 schematic with Snubber part from Carlos Filipe . And I've read many threads on these topics and believe that this should drive my EPOS M5 better than HK3480. Then I come up with the schematic and PCB layout.

The layout is double side plate through hole which I plan to have ground plane on the top layer. For your review I'ven't put ground plane in.

My question is
1. Will the schematic work?
2. Any flaw on the PCB layout and any improvement needs?

Lot's of parts. In my opinion you do not need all that.
My BPA is based on a simple design without the servos.
I use 0.1% resistors and then it seems that you do not
need the servos.

I use the DRV134 to drive each leg of the amp. It works
like a charm.
