Ok. Let’s try this again…RCA 9TC240 Alignment

[Chris K]

OK...not in any particular order...

1. How am I supposed to sweep the signal? The 2 frequencies, 22.05 and 24.75 are the peaks of the sweep in Figure 15 (and Fig 28 photo) and should be set in the marker generator correct?

2. Am I sweeping with a central frequency of 25mc a symmetrical sweep of 10mc? Is that what's required by the instructions "Sweeping 20-30mc" under the Sweep Gen Freq Mc column in the alignment table or am I reading that completely wrong?

3. Set bias -2V. Does that mean adjust the 250k pot for a reading of -2V at the R135-R136 test point as before?

4. Now for the biggie...shunt a 330 ohm resistor across the primaries of T-102, 103, 104 and 106. Does that mean connect 330 ohm resistors between the transformer tabs of the primary coils of all 4 of the transformers? How, solder them in? Please say no!
