I hate selling this amp and it is essentially new. However, I am relocating and need to drastically reduce my system to bare essentials.
You would be getting 2 full sets of brand new awesome tubes as well as a factory fresh 35 watt per channel amp that sounds delicious and is self biasing.
•Soft-start circuit Extends component and tube life by powering up the amp gently every time you turn it on.
•Tube plate fuse Protects the amplifier output stage. Other amps may need a trip to the shop if a tube fails. Not this one. Just plug in a new tube and fuse, and go.
•Adaptive AutoBias. Exclusive to PrimaLuna, this circuit monitors and adjusts bias automatically. Each power tube is monitored to stay in a peak operating range. Improved performance and better sound, with distortion reduced by 40 to 50 percent over conventional designs. No need for matched tubes. No bias adjustments. Ever. It also allows you to experiment with different power tubes. Plug in virtually any power tube. Adaptive AutoBias will automatically adjust itself! In addition to EL-34s, you can use 6550, KT88, KT90, 6L6GC, KT66, 7581, EL37, and any of their equivalents.
•Custom designed output transformers Encapsulated low hum, wide bandwidth for great bass and extended highs. Designed by Marcel Croese and one of the most prestigious transformer designers in the USA .
•Premium parts . Fully vented chassis, chassis-mounted ceramic tube sockets, Nichicon and Realcap capacitors. WBT style speaker terminals. Gold plated input jacks.
•Hand made with the finest point to point wiring, with workmanship equal to or better than any product you can buy at any price, period.
•Chassis made of finely finished heavy gauge steel, and five step automotive quality finish. Each coat hand rubbed and polished. Removable tube cage included no charge.
•Toroidal power transformer for low hum, and a front end that is dead quiet
