Try probing the IF from the junction of R327/8. But Scott tuners have critically-coupled IF stages and 1MHz bandwidth at the detector. You're not going to discover anything useful with a sweep of only 200KHz, and the shape of the bottom of the IF oscillogram is irrelevant, as it all gets filtered out.
