Transistor Schmitt Trigger Oscillator

I turned my Schmitt trigger from before into an oscillator. It doesn't quite behave the same, perhaps because there's now load on the output. I increased the resistor from base to ground to compensate.

Switch removed; it auto-starts.

Its an inverting schmitt trigger like 7414.

Yyyeah, but I thought of it more as adding an inverting stage because it needed it to oscillate. That was before I understood how badly the output needs buffering. The output load which I compensated for is the base of the 3rd transistor with its 10k resistor.
