F2 and UJN1208K

[El Reino]

Hello, my last amp was F2 and i think some mods. So what you folks think if i put UJN1208K place of IRFP240.😕

doable

UJN is normally ON device , so need negative voltage (ref. source) at gate for biasing

several ways to skin that cat

also , value of source resistor (group) needs to be determined with measurements , for preferred THD spectra

have you that equipment ?

I must test first and it's going to take some time. Sorry.
