Designed for relatively insensitive high Z microphones a gain control is provided the unit will enhance the intelligibility of voice signals considerably under difficult conditions. MIL...

Don't do it, chum We wound up on 75 meters tuned about where 40 ought to be and 40 was clear out of the tuning range. It seems that when you tie three grids together and ground them, usin four tubes in parallel, you have a plate to ground...
