The items for sale are all in perfect working order and very nice cosmetic condition. Only selling as I have bought an Aurorasound Vida. I was shocked how close this Luxman gear came in terms of performance to the Vida. Really very little between them.

Luxman EQ-88 Valve Phono Stage (MM only) complete with OPEQ-88 power supply and umbilical - £895 plus postage.

I bought this as New Old Stock in November 2017. I have the original Luxman boxes for both the phono stage and the power supply. Supplied with a trio of brand new JJ ECC83S valves.

Luxman AD8000 / 8020 silver wired Step Up Transformer - SOLD

A much sought after and rare vintage silver wired Luxman AD8000 SUT base with 8020 step up transformer. A silver SUT of this quality and performance would cost an arm and leg today.

A flagship Luxman SUT from the late 70s which provides an option for quick exchange of step up for different impedance pickups (you can find 8030 low impedance transformer and simply plug it in instead of 8020. There is also an 8025. More info:

http://www.thevintageknob.org/luxman-AD8000.html

Step-up ratio : 1 : 10 = 20dB
Optimum primary impedance : 20...40 Ohm
Input overload voltage : 70mV
Optimum secondary impedance : 47kOhm...50kOhm
Frequency response : 10Hz...100Khz (-1dB)
THD : 0,003% (1Khz, 200mV output at secondary side)
1Khz separation : > 90dB
Electromagentic shield : -95dBm (1œ standard magnetic field)
Weight : 100g.

I've spent a very pleasant afternoon with the Luxman AD8000 / 8020. I'm really pleased with my purchased. Hermit was a pleasure to deal with.

If the MT-88 is better than the AD8000 someone is in for a treat.

What the gain or step up ratio of the MT-88 SUT? Thanks!

Jerome, the MT-88 offers 26db of gain which I believe means the step up ratio is 1:20.
