Excellent condition, well cared for and never overdriven. Sounds great and has no functional issues. Includes upgraded tubes. Selling because Im getting close to retirement and downsizing. Listed on my friends account because hes an established seller and expert packer. Tube cage will be secured to the amp with plastic shrink wrap. Amp will be bubble wrapped, protected by large packing blocks, and shipped double boxed with double-walled cardboard. Tubes will be packed and shipped separately at no additional charge. Also have my Line Magnetic 211ia EL34 tube amp listed. Only flaw on this amp is a very small paint chip that occurred when loading it into a rack, shown in closeup photo with coin for scale. Chip could easily be covered with some touch-up paint. It wasnt noticeable to me once I stopped focusing on it, so I didnt bother. Comes with these upgraded tubes and stock 12AU7 driver tubes: • Tung-Sol EL34B Matched quad purchased from Upscale Audio Their labels with measurements are on boxes shown in photos. I also had these tubes tested before listing the amp. Measurements are written on labels in marking pen shown in photos. These tubes have better midrange clarity, while still being full and warm, and tighter, more extended bass than the stock tubes. • Gold Lion ECC83 / B759 (12AX7) Matched pair purchased from The Tube Store Their labels with measurements are on boxes shown in photos. I was surprised that driver (vs. power) tubes could make such a difference. They are considerably more detailed and clear than the stock tubes without any trace of being bright or harsh. These are the premium versions made in Russia as shown in photo, not the standard less expensive ones made in China.

The designers and builders of the PrimaLuna equipment all have a long history in high-end audio. We feel we have shown with PrimaLuna that we are able to offer a range of affordable audio instruments that can easily compete with today’s most expensive brands and assure you we will continue that way. We firmly believe that our quality level will set the bar at a difficult height for other products to match. This PrimaLuna Classic Premium Integrated amp features:Hand-made construction with the finest point-to-point wiring, using workmanship that is equal to or better than any product you can buy at any price.A heavy-gauge, fully-vented steel chassis with a five coat finish. Each coat is hand-rubbed and polished.Premium parts that include a toroidal transformer for power supply; custom designed -in conjunction with one of the most prestigious transformer designers in the USA- encapsulated output transformers for lowest hum; wide bandwidth for great bass and extended highs; ceramic tube sockets; ALPS volume control; Nichicon and Solen capacitors; superfast Philips-diode-circuitry; gold-plated heavy duty WBT style speaker terminals (all speakerconnectors are solid shaft, without hole, for better conductance, better sound and higher reliability); gold-plated panel mounted input jacks.SoftStart™ circuit for extended life of sensitive components, plus a reduced chance of tube failure from thermal shock.A new generation Adaptive AutoBias™ exclusive to PrimaLuna. This circuit monitors and smoothly adjusts bias constantly and instantly, reducing maintenance and increasing performance due to the dramatic reduction in distortion. It comes with a new extensive output stage protection circuitry with +B relay to protect output transformers, resistors and high voltage power supply in case a tube fails.The ProLogue Classic Integrated Amplifiers come with an EL34/KT88 bias switch. This means that with the flip of a switch you can choose for the optimum bias setting for EL34 type of tubes or KT88 type of tubes. No hassle with screwdrivers, no messing around with meters etc. Just switch tubes, switch bias!All new PrimaLuna PTP™ (Power Transformer Protection) circuit. When the power transformer overheats due to environmental circumstances, overloading or some problem in the unit, an internal thermal switch breaks the primary, allowing the unit to cool down before harm is done. After it’s cooled, contact is restored and if nothing is broken, the amp will repower and function properly.All new PrimaLuna OTP™ (Output Transformer Protection) circuit which further protects the amplifier.LIVE side of AC input connector indicated by aluminiumcolor screw.4 line level inputs
