hi apexaudio
greetings just want to confirm a few things
1 R 100 is .47 ohms R52 4.7 ohms should be of same value what is correct value
2 how to identify 1 WATT RESISTANCES in vertex schematic i am thinking
longer resistances with no markings in resistor symbol is 1 WATT the smaller
resistor symbols have a dash in them is .25 watt can you please help out

thanking you

Use MUR120 instead BAV21. With two fan cooling your heatsink is OK.
