I have a 2252B and 2330B receiver, and on the weaker college jazz station the 52 is as clear as a bell, but the 2330 has a good bit of static. Is this something that goes with the territory of a 2330B vs. a 2252B, or does the 2330B need some type of service? It's been "gone through" when I purchased, but it may need a refresh?
TIA!
