Default Re: Bach with sparks!

Hey Albert, I just noticed a few things:

*there doesn’t appear to be a DC bus for the MOSFETS.
This could cause a headache or worse. It needs to be really well designed .

*there are resistors in parallel with your pulse capacitor. This is unnecessary, it’s not a DC component , and turns a critical LC circuit into an RLC circuit and will cause irregularities.

*there is no RF ground plane . You need a good one and the MOSFETs’ survival depends in part on this.

At moment it looks like an audio circuit, with loads of stray inductance / long leads which will likely blow things sky-high immediately you power up.

Where is the driver for the MOSFETs and what configuration are they in?

I’m away for a few days so won’t notice any post but thought I’d share some thoughts to save a headache or two .
