Well I have a GE200 which we replaced the capacitors on, cleaned, lubed, tubes checked and a couple replaced and while it plays great above 850 below 850 we get squealing, and very poor weaker reception. Any possible suggestions for a cause/solution?  It is a 6 tube AC/DC set in prettty good shape overall. This seemed a simple enough job but this is the hobby that humbles.
