I don'd know what a 774 is, but I had an XB with a similar problem. Solution?. Turn the ferruled cueing pin that sits inside the post that the tone arm rests on 1/8 to 1/4 turn anti-clockwise. As time passes by, the arm will again not rise to full height, so repeat the process. Worked for me. In fact I think it was in the manual.
Cheers
