tained at the same time.

The FM section Includes an entirely pro-wired and m:
aligned front end" housed end completely shielded In a
solid aluminum-zinc outing. This 'tront-end not only

entIrely stable and guaranteed drift free by virtue of the
most advanced circuitry and temperature-compensated
components. Just as In the costliest and finest PM tuners
available, noKFC is used beamsenon'e is neefid. Other

FM performance features include stabilixed lowilmitlng
threshold for excellent performance from weaker signals
and abread-bmd ratio detector for improved capture ratio
and eater tuning.

Precision eye-tronic" tuner is employed on both FM and
AMusing the DM-7fl traveling eye Indicator that contracts
