DC to AC inverter using 555 timer

Click For Summary
SUMMARY

The discussion focuses on the use of a 555 timer in a DC to AC inverter circuit. It highlights the necessity of incorporating a power amplifier to enhance the output power of the 555 timer, which is inherently a low power device. Users are directed to a specific schematic link for further details, although the schematic was noted as unavailable. The conversation emphasizes the importance of understanding the role of power amplifiers in conjunction with the 555 timer for effective inverter design.

Your schematic is not available. The 555 is a relatively low power device, so if you require it to deliver much power output, you need to follow the 555 with a power amplifier.
 
Most likely this can only be answered by an "old timer". I am making measurements on an uA709 op amp (metal can). I would like to calculate the frequency rolloff curves (I can measure them). I assume the compensation is via the miller effect. To do the calculations I would need to know the gain of the transistors and the effective resistance seen at the compensation terminals, not including the values I put there. Anyone know those values?
