Agree, check above suggestion, problem is most likely "left" of the IF. Make sure Loop antenna and antenna coils are connected properly and shows continuity. Voltage checks should be done as well. See if connecting a length of wire to external antenna changes anything, and if you have a known good one, swap out the 7A8, as they can be difficult. Many now replace the carbon resistors whilst doing a recap job.
