Super rare find from an avid Jadis collector who was in the process of putting together a huge Jadis system that was unfortunately never finished.

These are their 845SE tube based monoblocks amplifiers. This model is also no longer in production.

These are also 110V which are even harder to find.

Retail price in 1992 was $20,000 (over $38,000 in today's dollars).

And we actually have another set of these amplifiers in the same condition, PLUS one more set that are barely used/mint.

We hooked the barely used/mint setup up to our Wilson Audio X-1 Grand SLAAM speakers for testing and were treated to the best dynamics and ease we've ever heard from them. By FAR.  

Please note due to size and weight this item is not covered under our free shipping promos that we offer from time to time.

This will ship for $450 flat rate freight anywhere within the lower 48 US States strapped to a pallet due to its weight and for safe travels. If you're on the East Coast contact us before your purchase to double-check this rate.

We strongly recommend 2-3 friends to help you unbox safely on arrival.

The SkyFi Testing Process for Tube Amplifiers:
We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and tubes are inspected for signs of stress overheating or cracking.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If it all looks clean we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier the remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will also be tested.

We also test all tubes for output gain and leakage on our calibrated and modern professional tube tester against the original manufacturers specifications. If needed, the tubes will be replaced from our vast NOS (New Old Stock) vintage or modern inventory. 

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage Kef speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
