Jadis JA80 Tube Monoblocks w/Sound Anchor Stands - Made In France

Amazing sounding set of tube monos from Jadis.

If you've been eying our set of remarkable 845 Jadis monos but need a bit more power, this might be the perfect solution.

These are cosmetically near perfect and will come with matching sound anchor stands that are a super match for getting them off your floor.

The current model of these monoblocks retails for over $25k.

Configured for 8 ohm output.

Technical Note:
Cathode resistance was changed from a stock value of 3.3 ohms to 4 Ohms by an authorized Jadis service center to allow use with 5881 tubes prior to arriving at SkyFi.

Our testing was performed with KT88 tubes and the bias level achieved with the altered resistors was acceptable for proper performance.

Both amps tested to 60W of clean power per channel before clipping. The original owners manual claims that these are 80W amplifiers, but all of our searching indicates that true RMS power is 60W.

Shipping Note:

Due to the weight and fragile nature of these tube amplifiers and stands, these will ship freight anywhere within the lower 48 US States for a flat $600. This figure includes full insurance, and this freight charge will be added during your checkout.

These are also safely packed and palletized to ship worldwide, just contact us for a quote. Pallet is 240 lbs with dimensions of 40" x 48" x 33" (W x D x H).

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 B&K 747 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.
