Hello, this is my first post, so please feel free to advise on etiquette. As a disclaimer, I've got a little bit of EE experience under my belt from some of my simple past projects, but the bulk of my knowledge is still in theory. I started working on a 555 driver for another project but got kind of backlogged, I've been experimenting with it again and found that I am getting acceptable output up to the pins of the MOSFET, but after that nothing on the secondary. For reference, the transformer I'm using was a double tap 12.6 - 0 -12.6 to 120 V, the MOSFET is an IRL7833, which appears to be suitable for logic level applications. I've pretty thoroughly checked my solder joints and replaced some components, perhaps somebody more experienced can give assist me.
