The 12AX7 cathode follower is used to not only handle these peaks but primarily to provide a relatively low d c impedance to ground for the 1614 control grids This low impedance is necessary to prevent a change in bias for the 1614 tubes due to reverse grid current Such a bias change can cause excessive plate and screen dissipation in the Youguang Guo (S'02-M'05-SM'06 IEEE) was born in Hubei China in 1965 He received the B E degree from Huazhong University of Science and Technology (HUST) China in 1985 the M E degree from Zhejiang University China in 1988 and the PhD degree from University of Technology Sydney (UTS) Australia in 2004 all in electrical engineering

Relays are generally used to switch smaller currents in a control circuit and do not usually control power consuming devices except for small motors and Solenoids that draw low amps Nonetheless relays can control larger voltages and amperes by having an amplifying effect because a small voltage applied to a relays coil can result in a large voltage being switched by the contacts
