Hey Everyone,
I hope someone can help . . .
I built the following inverter (see image) using 2N3055 transistors and a 60 watt transformer (12-0-12 VDC, 120VAC). The problem that I ran into was that on the transformer's output, it was able to power a small 120Vac 0.025 A neon light bulb. But if I used a 120Vac 15 Watt Incandescent light bulb, nothing would happen. (The entire circuit would continue and it did not shut down.)
I figure with 2N3055 transistors, the astable oscillator would be powerful enough to drive a simple light bulb. So my solution then was to use the same type of transistor as a current amplifier. Which I have all the parts arranged like the following to bias the transistor:

Unfortunately, when I connected the collector to the transformer, the transformer didn't output anything. What am I doing wrong here?
Also, I'm using a 2n3055 transistor on each of the yellow lines going to the transformer and arranged in the same way as in the link provided.
Lastly, I am using a 12 Vdc 200 amp hour car battery . . . so I have a good power source. And I tested each transistor . . . they are working. If I can't get this to work, I wonder if perhaps I should just use op amps, but I would like to make this deign work
In the end, I look forward to your replies.
PS. I tried a biasing calculator . . . the results from it were no luck.
