Arkless Electronics
Trade: Amp design and repairs.
This was a commission to add MM phono to an MC equipped Exposure 17 pre amp. An MM board was first designed for it and built up after extensive measurements of the original Exposure MC board and RIAA stage proper to get the gain structure correct. The "Tape 1" input is re-purposed as MM in. A small relay directly between the MC board and RIAA is used to switch between the MM and MC board outputs and is controlled by a small toggle switch added to the rear panel.
Et viola! MM and MC facilities selectable by rear panel toggle switch. As good an example as any of the "if you can imagine it" modifications available from Arkless Electronics.
