- Good morning and evening! Here is grid bias power supply in G3SEK's control board I do not understand how it works. I think it is not a regulated power supply. If it work, should be modify as red lin

- Thanks. Most of amplifier only use one transformer, the secondary's Voltage can dip about 15- 20% when full load. If it did not regulated,the bias Voltage will chage. I think the ruglated power suppl
