Hi , Wojtek !
Of course , I have some ideas how to modify this tuner , but before doing it you need to check if it operates correctly ! I mean tubes health , power supply operation , DC voltages on testpoints , LC tanks alignment , etc . You see , if we modify the faulty or bad aligned circuit - we can go to wrong direction . By the way , the great device for tuner alignment is RF sweep generator ..... do you have it ? If you do , it's very good ! But if not - you can control only DC parameters , and cannot find out possible problems in RF and IF stages .....
Best regards
