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

A caution I need to add with this particular chassis when adjusting the IF stages. The adjustments can be deceptive because when you are adjusting for a peak you may inadvertently be tuning two stages to the he same frequency which will cause oscillation. This oscillation can be easily mis identified as a peak. The way to confirm is always as you raised or lowered the deep generator input, the output put level should rise and fail. If when reducing the signal generator in you still see a signal which does not change when you vary the generator output, you have an oscillation condition you will need to address.
