Good morning and evening!Here is grid bias power supply in G3SEK's control board :http://www.zmdz.com/bbs/incomefiles/20144/1912574624747.JPG I do not understand how it works. I think it is not a regulated power supply. If it work, should be modify as red line marked and replace NTW5142E by TL431(adjustable) or TL431 series a zener(higher volt) Hsu _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
