1961? Zenith C845Y HI-FI AM-FM Tube Radio Issues

[vortalexfan]

Greetings everyone, I just acquired a 1961 vintage Zenith C845Y AM/FM tabletop radio that I had replaced almost all of the paper caps in it except 2 of them because they were in difficult to reach/access locations in the radio, and the radio tuner is extremely out of alignment, especially on the FM Band because stations that should be on the lower end of the tuning dial are showing up on the middle of the dial and stations that should be in the middle of the dial are showing up on the top of the dial and the stations that should be on the top of the dial are non-existent, also the audio quality coming out of the speakers isn't quite up to snuff to where i would expect the audio quality to be on this radio. What could be causing these aforementioned issues with this radio? I was thinking possibly the IF Alignment is way out of adjustment but I'm not sure if that would cause the lackluster audio quality issue, and more the dial alignment issue.

Any help would be appreciated.

Thanks.

Local oscillator alignment is usually what causes off frequency tuning, though if this has AFC try turning it off to verify local oscillator doesn't snap back to normal.... AFC takes detector voltage and uses it to pull the local osc to peak signal... If the AFC bus is wildly wrong it might be able to feign a non-existent local osc alignment issue.

Not a bad idea to atleast check IF pass band with a generator too.
