A lot of truth in that statement.
I've never had problems with the large IF transformers in Zenith AM-FM sets. Mostly in the AM only sets. The IF cans are simular. But then, again never say never.
The 845 series, was unique in the fact that it has two stages of IF, for the AM stage. Only found in the higher end communication receivers.
