I bought this RA1 brand new to pair with a PS500 I owned for approximately six months during 2017. In that time, the RA1 was used only with the PS500 and received less than 50 hours of use. With the PS500 gone, I no longer use this amp in any of my setups, and would rather pass it on to somebody who will enjoy it more often. The new cost of the amplifier was $350, and I am offering mine with minimal play time and zero cosmetic wear for $150. Payment will be accepted via PayPal or Google Wallet. I will ship for free to anywhere within the continental U.S., but the buyer will have to pay for shipping elsewhere. Be sure to let me know if you have any questions!
