Upgrading the VHT "WATTS" Circuit
#6
Hi Guys

The gate-stop must be there, as well. The SB-style circuit had that. The resistor helps protect against oscillation. The zener protects against voltage spikes.

The frequency of oscillation can be in the tens or hundreds of MHz and your scope may not show it but the mosfet will overheat and likely die.
