The electrolytics reformed but they are still very likely to short again. And you can't tell if a can needs replacing by looking at it

IF cans ? I think you are mixing terms. IF cans are the transformers coupling the Intermediate Frequency amplifier stages.
Also you really can't properly test electrolytic capacitors with a voltmeter. You need to use a capacitor tester that put the full working voltage (e.g. 450 volts) across the cap and checks for open, shorts and leakage.
