For matching a
range of moving coil Phono cartridges to
balanced or single sided solid state or valve pre-amplifier. Suitable for
cartridges with a self impedance in the range 1 to 100 ohms. Ensures
appropriate loading of the cartridge and correct matching to
pre-amplifier. When used with a 100K ohm secondary load the cartridge will
see a loading of 1000 ohms. Lower secondary loads may be used if
some damping is required. Ideal for use with high or medium output cartridges
provided the output voltage and pre-amplifier gain is adequate for a 1:10
ratio. Two transformers are required for a stereo system.
Replacement for type 6495 which is now obsolete.

Mumetal (76%Nickel) laminated core for minimal
harmonic distortion and exceptional bandwidth. 4 separate electrostatic
screens for rejection of hum and noise in the cable connecting between the
cartridge and transformer. Multiple interleaved windings ensuring
exceptionally good bandwidth. The high bandwidth and very low phase shift
ensures excellent transient response. Mumetal can for magnetic shielding.
Available with various package options including an international octal plug.

NOTE The cartridge should be
connected to the White and Yellow leads. The amplifier should be connected
to the Pink and Mauve leads. The Black (ground) lead is normally connected
to the signal ground of the amplifier. You may need to experiment with
different ground connection points to minimize hum.
