” original Mk1 Maths with evil red LEDs. Minor rack rash and some small hairline scratches, otherwise cosmetically perfect.
This unit has a small problem with the Channel 4 output, in that it produces a tiny but constant bias voltage. If Channel 4 is controlling a VCA, for instance, this will result in a small amount of bleed when the VCA should be fully closed. the bias is very slight, so much so that the issue is inaudible at normal listening levels, and I used this MATHS in my personal system for many years without issue. nevertheless i’m listing it at $50 below the going rate.” Click here to search for synths on eBay
