This one is in excellent cosmetic condition and working 100%. It has just been professionally serviced and with some restoration. As the title says, this one has the mLab Midi box plus the newer, Techsmechs TM-8 Keyboard. This keyboard is a huge improvement compared to the original. Please check the Midisoft.De website for the midi specifications. This midi kit is much less invasive than other kits as you do not need to add any midi ports/holes to the unit. It plugs directly into the "computer interface" on the back of the OB-Xa. Local pickup is welcome in the Los Angeles area. I will ship to most countries, but to be sure, please ask. Shipping overseas will be expensive so please be aware of this. If you're in the USA and the shipping cost is less than the price shown, you will be given a refund. I have this marked as a US sale only. If you're overseas and interested, please message me and we'll set something up.    Not sold as-is!

Cosmetically - Nothing is mint in my opinion and this one is no exception. It is very clean, but please check out the photos and judge for yourself. It's definitely one of the cleanest that I've owned and I've had many. I received this one from the original owner who rarely used it (and it shows.) The original wood sides were refinished and it has new screws & washers. 

Internally - Apart from any repairs, it's been disassembled and cleaned, all potentiometers, switches, and panel controls cleaned, the power supply has been rebuilt (new capacitors), the bridge rectifiers have been replaced, all internal connectors were cleaned & re-seated, the battery has been replaced, the Techsmechs TM-8 Keyboard installed, and it has been fully calibrated. A single resistor was added internally to power the mLab Midi unit so you don't have to use an external device to power it. This might updated as I'm probably forgetting a few things.
