Kai, it does sound like you need to re-peak the preselector trimmers - I am
assuming that your response on all the other bands is okay.
The meter should be close to S9 on 20 with the calibrator, but it has been
normal from what I have seen for the level to fall off with increasing
frequency. With the A-Line, only getting around S5 on 10m has been pretty
typical for me.
Check your signals on each band against what you can receive with your other
rig(s). The calibrator sometimes isn't as strong as it "should" be, but the
received signals are fine.

Subject: [Drakelist] Some advice needed with R4-A
Hi
I own a second-hand R4-A which I seldom use with its pair T4-XB.
Being unused for some time I noticed that the R4-A lacks sensitivity on 20
metres. Perhaps on 15, too.
I used the calibrator as reference to make sure that the rx is not
completely dead. The calibrator makes the s-meter deflect to say, about
three or four S-units, on 80 m it is well above S9.
Another rig, FT-920 picks up signals equally well on 80 m band but beats
Drake on 20 m. Drake doesn't hear anything except the calibrator.
I went thru the ganged wafer switches with a cotton swab and DeOxit (red
fluid). No go. I also replaced the rf amp valve, the one with spring
loaded shield on it with no luck.
Please help me if you can. I simply love my Drake line and won't give up.
