    Circuit Description — Type 130 is practically symmetrical, regardless of the frequency, V15B holds the right-hand end of C90 at about +150 volts when the ADJ. 1 control is properly set. during the negative excursion while the multivibrator pulls down the left hand end to about +100 volts, thus charging The multivibrator is arranged to shift rapidly from one C90 to about 50 volts.
