analog inputs. The right channel is marked with
a Red band and the left with a Black band.
Loudspeaker Connection
The loudspeaker connections use one of the
two pairs of output jacks behind the output
transformer on the top plate of the chassis. The
output jacks accept many types of wire
termination, although we recommend either a
high quality spade lug or the use of simple tinned
wire terminations for this hookup.
Determine the nominal impedance of your
loudspeaker. The 8 ohm switch position should
be used with loudspeakers which have greater
than 6 ohm minimum impedance. The 4 ohm
position should be used with loudspeakers with
3 to 6 ohm minimum impedance. The impedance
selector is between the loudspeaker outputs.
Power Switch
The rear panel power switch marked 0 1 will
take the amp out of standby when switched to
the 1 position. The input tube filaments are
always powered to insure a gentle turn on and
instant sound output.
