My immediate reaction was that, since these are used for the 
SM220/BS8, the output would be before the filters. A quick look at 
the TS830 service manual confirms this. IFO1 is taken directly in 
front of CF1, the ceramic filter which precedes the Xtal Filters.

IFO2 is post detector.

Hope that helps,
