Well, there still may be a thermal effect. It is hard to imagine a time constant of several minutes that is due to a capacitor, while a component or sub-assembly will undergo such time constants. If you have some cold spray, you might try a short blast in specific areas to see if there is a dramatic change.
As for what may be the root cause, I would check for evidence of a carrier bleed-through or spurious signal or a possible weak oscillation that is getting through the IF chain and getting rectified by the AVC detector (in other words, masquerading as a real signal).
