The MX-1 was tested for correct operation in October 2020 by Alan Kendal.
The amp was biased to Yamaha specifications. (I have the service manual.)
All components were tested to be within tolerance.
The amplifier was put into storage after the inspection and has not been used since.

The amp is 25 years old.
This unit is a 230V European model. I'm informed that the design factors are sufficiently wide for operation at 240V to be within safe margin.

Ideally, collection from Cardiff.
Payment via PayPal, please.
Carriage is extra, and because of the value and mass of the unit, I'm willing to arrange for a self-employed courier to collect it from my place and deliver to your door, in a car and with care (mainland UK).
I'll ask for £65 towards the cost of this and cover the rest of the expense myself.

Please get in touch if you wish to discuss more about the MX-1.
