Yes, its got metal walls between the coils linking the RF amp
and mixer stages, how it gets any RF through is hard to figure.
I think its also got metal walls between the antenna input and the rf amp,
yet seems quite sensitive on the lower bands.
Good audio, with a nice modern full range speaker in the front, the
cabinet makes a good speaker cabinet.
