Useful extra user functions , so owner wants repair
Does anyone know if the r/c receiver marked "sensor" also has a function
controlling the lamps on the front, for varying room lighting?
R/C tr and rx are both early almost discrete components

This deck stopped responding to the r/c.
Transmitter was ok , receiver diode ok but nothing coming out of the first
op amp. The o/p is dc coupled to the next stage.
Replaced the LF357 and m/c works all functions but only in subdued lighting.
If room light is too bright then there is not even manual control of the
deck functions let alone the r/c, kill the room lighting and normal service
is resumed.
