There may also be an issue with the AVC bypass capacitor, it could be open circuit or missing. Another thing to look at are grid caps and grid cap leads, sometimes the solder joints on the grid caps get flaky, as does the solder joint on the clip that goes on it, the wire can also break internally. Another source of oscillation can be the first audio tube, if it is a glass type like a 6Q7G or a 75 they cause a squeal with the shield removed.
