What's hard about it? First make sure you are tuned in, if in doubt inject composite into the video amp tube to eliminate the tuner/IF as a fault. Then zero beat the 3.58 osc: short the reactance tube grid to ground, then adjust the osc slug till the bars slowly float by. Remove the short and tweak the CW trans (top and bottom) till the bars look correct. Helps having a reference monitor to look at while doing this, so you don't get confused. It doesn't get any simpler than that, or at least I haven't found a better way.
