My nightmare set: RCA 9T240

[Electronic M]

The sound is probably similar to my 8TS30...I had to align the audio on it. I tried the sam's non-sweep generator procedure (since I don't have a working 20MHz sweep gen), and while I could peak the system on freq, the audio carrier from the tuner wasn't on freq (thus no sound). Eventually, I started repeating peaking the system off freq at several KHz intervals above and below correct freq until I found a point where I could get a bit of audio from my agile modulator at some fine tuning setting. I then peaked the IF to the program audio by ear, tuned the generator to the freq I peaked the sound IF at and peaked the IF again...Those big unshielded coils on/near the tuner did need adjustment in the process.
