Graham Slee Elevator EXP MC Step-Up Amplifier

Description

Elevator EXP

The Elevator EXP by Graham Slee is a specialist phono stage step-up amplifier which will give you hum-free sound, purer bass, greater definition and much more of your music.

In the beginning you would have to buy a step up transformer (SUT) to be able to use a moving coil cartridge. But they hummed and did strange things to the bass. The Elevator EXP changes all that.

Moving Magnet Does Moving Coil

Elevator EXP is designed to step-up the tiny moving coil signal to the moving magnet level of a hi-fi phono amp input.

Whereas some moving coil cartridges will happily give their best with 100 Ω loading, others can be quite particular. Rather than fiddling around with links or DIP switches, the Elevator EXP gives you all its loading options up front, right there on the front panel – making it easy to get your sound right.

Cartridges

You can use any low output moving coil (MC) cartridge with output in the region of 0.15 – 0.8 mV (ref 1kHz at 5cm/sec).

The Elevator EXP must always be used between cartridge and a moving magnet sensitivity input. It must never be used ‘post EQ’ – after the moving magnet phono preamp.

Power Supply

Elevator EXP is supplied with the PSU1 power supply, or optionally the upgrade PSU1 Enigma version.
