It looks to me like the reason those wires snapped off is due to the 4 springs not holding that inner coil / spring tray up off the case of the pan , as I see it sitting in contact with that case and it should not be.
A condition like that will keep snapping those wires off!!!!
Those 4 springs that should make that inner tray float may be shot , or just not in the right location holes in the case to make the tray float .

You also test can those coils with a ohm meter to prove that they are not open in the first place, as many times they go open , but with those type connectors that is a far smaller thing.

As Bill posted resolder them carefull as also you may unsolder the super fine wire that they are wound with when soldering those main leads back on.

Did that pan have a dark gray pressed paper glued on its top, as I do not know if those type of solder on coil terminals are original , that pan may not work with your amp even if the coils are good?
Each coil should ohm check in at between 175 and 190 ohms if that pan is to work with the amp.

Also a very important thing is when you remount the pan in the amp the end of the pan marked output needs to be on the side of the amp that the power transformer is not on, unless you want a hum making monster when you turn the reverb level up.

In regards to your non working tremolo I have a k200 of my own that is doing that same thing, but mine has just a tad of tremolo when the control is on full and I can hear that the speed control is working normal.
I need to make the time to get back to trouble shooting mine now that Summer has ended .

Another issue with any pan sounding crappy is those coils themselves floating some on there iron cores.
If you get the pan working use gel type super glue to hold them tight to the core.
