I have up for sale my Vac MK 3 preamp in excellent condition. There are no visible scratches and this preamp has had light use. It is only 2-3 years old and I am currently using Psvane tubes (included and installed within the unit). The tubes have about 400-500 hours of use on them. This was used in a pet free and smoke free environment. Everything is included including the power supply, remote, instruction manual etc. The shipping box is also in great condition and this unit with be insured when shipped. If you do your research on Vac equipment you know how amazing they are. Also, this unit was sent into Vac about 1 year ago for the caps and resistors to be upgraded. It made its sonic signature more warm, yet detailed and more natural. This pre amp is truly a world class pre amp and you will not find anything better at this price point. The tech support from this company is also truly outstanding if a problem would arise in the future. Please buy with confidence as can be seen by my feedback. Please no low ballers. Add 3% PayPal fee.
