in all ranges of single conversion it works allready.
in the ranges upside, means double conversion, there is a lower sensitivity, I am thinking for tired tubes in the IF stage 1 = 3MHz

The PSU was removed and all electrolytics checked for capacity and isolation.
The scaling works exactly.

I have to buy tubes, they are not in my stock bec. the radio use allover SQ, like EF805s, ECC801s, E180F and so on.
