Can someone help me figure out why a simulated circuit I made wont work on Tinkercad?
1) Since Vbe > Vce there is a reverse polarity on the e-Caps.  In practice tantalums can handle 10% reverse voltage, not sure about Alum.

There are ways to avoid this adding diodes to Vce. 

2)  Current gain must be 33%&lt; Ai&lt; 50% of hFE as rated  saturation assumes 10% hFE.

Otherwise It wont saturate or demand too big a cap.

Change 47k to 30 k



Darlingtons work the best.
