The PCB design shows two wires connection to GND from Top are they jumper wires or fuse connection?
Can I use 1N5408 instead on 1N5404 diode?

Can I replace the power, supply with ready made switching power supply of 35v not dual only plus and minus out put, no earth connection the reason I cant find transformer with 35v dual power supply, or too expensive and too heavy.
Thank you.
Your reply and help is very much appreciated.
