My guess is that the antenna tuning is not in parallel with the oscillator tuning. By skipping the antenna tuner coils you claim to have more sensitivity.

So the antemnna tuning needs some adjusting, this can best be done according to the service doc.

In general, tune in to a low frequency in a band pe MW.
Adjust to max reception (or noise) with the relevant antenne coil for the band.
Now tune to a high frequency in this band. Adjust the cap in the relevant antenne tuning circuit.

Before doing this, if possible, check if the tuned frequency coincides more or less with the scale.

A signal genearator might be helpful, but if you are aware of the stations and frequencies in your area you can use that.

Better leave the IF tuning as is in first instance.
When you have a signal generator you can check IF first.
