Texas Star 350 HDV PRE AMP Not Working

[BOB 547]

Need help with my Texas Star 350 HDV
PRE AMP not working the light turn on but when I press the switch in the receive
drops :bdh:

 

[loosecannon]

first thing to check is Q2, the receive pre-amp transistor.
use this diagram to find it:

it is a 2N4125 transistor, or you can use an NTE159.

here is a schematic:

if Q2 checks ok, try D2. if thats not it, move on to the components around those two parts.

usually its the transistor.

Replace preamp transistor its a common part failure when these preamps fail.

 

[VA3ES]

It may continue to fail. The sequencing timing on these amps is terrible.

What does it mean if you push the rec amp and the signal meter goes up but the signal you were listening to disappears?
