Not really. I'm writing it for the 100th time like many other members: an old, high voltage MOSFET has slow body diode which makes it a bad solution in such a simple output stage. IRF360 has a Qrr of 5.6 uQ, and high channel resistance, so it's a really bad MOSFET for this circuit!
I said you should choose the LOWEST voltage rated device which meets the requirement!
You can pick up irfb4227 at Farnell United Kingdom | world-leading distributor of electronic and maintenance, repair and operations products.
Or RS Components | Electronic and Electrical Components
I use irfb4019 as these are low gate capacitance yet will still drive 17 amps.
They are both international companies.
IRFB4019 is just over a pound each.
RS has no minimum order charge.
Farnell min. order is £20.
On this link you have interesting information about toroid cores

Core form PC and from my picture (2.7 x 1.4 x 1.1cm) is actually IRON POWDER CORE 106-26 yellow-white (Al= 900uH/100turns)
Now I do not understand this calculation for 20uH coil and this core
N=100(L/Al)^1/2
=100(20/900)^1/2
=100(0.02222)^1.2= 15 turns
Why 17uH on this core has 23 turns and gap of 1mm????
But I made 23 turns with gap core (in atached pictures), wire that i use is 2x0,8mm
