Traced the problem of my FTS 1200 to the first BC109 Transistor on the  
A2/A3 AGS/Amplifier board. Since it is right after the Oscillator transistor 
low  noise is critical. This unit is at least 30 years old and my question is, 
what  transistor will have even lower noise than the than low noise BC 109. 
Voltage is  6.43 V.
Thanks  Bert Kehren
