INTRODUCTION
E50 FM TUNER
INSTRUCTIONS FOR USE
Thank you for purchasing the Musical Fidelity
Elektra E50 FM tuner. Used properly and carefully, it
should give you many years of outstanding musical
reproduction.
The E50 is the result of many years painstaking
research and development. It is designed for ultra-high
definition performance.
Aesthetically, the E50 is a perfect match for the
Elektra E10 or A2 amplifiers and the E60 or A2 CD
players. Together, they form one of the finest hi fi
systems that you can own today.
Dust regularly with a soft duster or soft brush but do
not use cleaning or polishing agents - they may harm the
surface finish.
If you have any questions about anything in your
audio system, please consult your dealer who is there to
help and advise you.
