A Solid State Replacement for the 62 set dynamotor
... I built an astable multivibrator using a pair of BFY51s, set to switch at about 50Hz by judicious choice of base RC values. The output voltage of this is used to switch on and off alternately a pair of TIP3055s. These alternately earth either end of the two 9v windings connected as a 9V-0-9V primary ...
