This ad is for one EAR 509 100W monoblock valve/tube power amp. It was recently serviced and all faulty electrolytic capacitors replaced. 12AX7 tubes were also replaced. This amp is powerful, silent, and produces sound well worthy of its reputation. Decided to go the integrated route so no longer have the need for this particular piece. Shipping cost is an approximation. If less, I will refund. If not significantly more, I will cover the difference. Power output (20-20KHz): 100W into 4 & 8?
