Frankensteins LC plus opAmp monster

Edit: I wish someone here would have just told me WHY opAmps cannot deliver current to match their increased voltage output. It makes it confusing when a student is learning electronics why all of a sudden this apparent discrepancy occurs - here's your increased V - but sorry, the way it's obtained you cannot deliver it the same as a battery or other V source. I really like this app as a learning tool but this is an area where it could use improvement. OpAmps deliver high V outputs limited to their (not the circuit's) V source, but because of the way it's obtained cannot deliver higher currents to power loads. Instead, the app treats the output of the opAmp as a legitimate V source with no limitations on current. This was an experiment. I was told I can't use a load to directly pull too much current off a regular old op-amp, as it's likely to be damaged. Will a diode work to protect it? Adding the diode meant the return of flashing to my lamp. Adding the extra (2)caps (1mf/800uf) and reducing the L and C of the oscillating circuit created what is seen here. Basically a lamp when disconnected from main circuit V source doesn't turn off. Notice the current in the inductor (green indicated) doesn't diminish either from 206mA (edited as I changed circuit). If this actually worked in real life this lamp would be powered by just a few mA or several uA from the VCC of the op-amp. I don't know if it does. Hit the SPDT switch briefly and back again to bring power to the beast.
