Hi all, does anyone know the number of Q101 on the main board. The sub in, off of the input board, is fed to this transistor through a resistor and cap. The transistor is shorting the signal to ground. The number on the transistor is BA21. I tried searching specks for this on line. Any help would be appreciated. Thanks.
 
Is this an smt? If you a post pic of the board and a close up of Q101 and surrounding circuit I may be able to identify part. I will check schematics.

Also,check the DC voltages on all the pins on input board, black probe on one of the transformer center tap leads.

The J108/109 appear shorted when there is no bias voltage on their gate.

Fairchild often puts the part number below the production code.
