PrimaLuna ProLogue Premium Power Amplifier- Silver Fronted Finish - Ex Display

With EL34 Valves.  Excellent Condition. With original packaging.

This PrimaLuna ProLogue Premium Poweramplifier 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 the quality of which fits nicely between standard ProLogue and DiaLogue transformers; 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 speaker connectors are solid shaft, without hole, for better conductance, better sound and higher reliability); gold-plated panel mounted input jacks.

  • SoftStartTM circuit for extended life of sensitive components, plus a reduced chance of tube failure from thermal shock.

  • A new generation Adaptive AutoBiasTM 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. In all ProLogue Premium Amplifier models the new generation Adaptive Auto Bias Board comes with our new BTITM circuit. BTITM stands for Bad Tube Indication (by LEDs), making tube-life again a bit easier.

  • All ProLogue Premium 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!

  • This ProLogue Premium Poweramplifier comes also with a mono/stereo switch giving it the functions of both the ProLogue Premium Mono Amplifier as well as the ProLogue Premium Stereo Amplifier.

  • PrimaLuna SilverLabel tubes are pre-selected by us following our simple 60 out of 100 rule (PTSTM - Premium Tube Selection) and as such, are already “special” when compared to other standard tubes on the market. Additionally, for certain models we have our GoldLabel tubes, which are available from us and several other parties if you wish to upgrade. In the USA, Upscale Audio's inventory of New Old Stock tubes (which is another thing you might want to experiment with) is the largest you can find. Elsewhere, independent suppliers can assist you to make your best choice.
