just looking at a 19" go5 black and white vector monitor

the high voltage section and main board look to be the same as a 15" are they the same?
 
Almost. The -805 (15") deflection board has 750Ω resistors at R604/R704, while the -802 (19") has 910Ω @R604 and 820Ω @R704. The HV board is the same.
 
I notice there seems to be 2 types of flybacks in the go5
one is a bit bigger is that a more fail safe ver?

I haven't looked closely. The HVTs in B&W vectors are uncommon failures; the weak point is the HV diode, which is in-line between the HVT and anode. I don't think one version is better than another.
