Re: V6.1 Blown output transistors and pcb trace #v6 #ubitxv6-help


Stan, one of the reason that IRF fail with a huge current draw is cased by gate
being disconnected or bias being too high.. Rv2/3 ground going open.

On many of my experimental boars provided by Farhan/HFsignals I have abuse,
not a single uBitx blew and only one Bitx40.

I dont agree with support saying 13.8v is high.. I have been running boards on 15V.
The PA can handle 24V.
