Luxman MB88 Vintage Tube Monoblock Amplifiers - Rare USA Find

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

The MB88 is a monoblock amplifier made by the renowned Japanese audio company Luxman. 

It was hand made in Japan from the highest quality materials of the time and benefits greatly from the quality of the transformers in particular, which contributes to the lush warm dynamic sound quality. It uses point to point wiring throughout.  

Luxman tube amps from this era are a rare find in the US.  Most were sold overseas and kept in the Asian market.  You can buy them from Japanese websites, but it will cost you an arm and a leg and may not be the correct voltage.  

This is a 100V-115V version that has been well cared for and babied.  It was part of a large collection that we just purchased from a local collector which included dozens of amplifiers, so you can imagine how little use it saw.  

Overall physical condition is good but there are a few scratches or scuffs throughout.  The grill cover is in rare good shape as most are bent and rusted over time.  

On the back you’ll find proprietary speaker jacks but I have included high quality converters that allows you to use spades or bananas for all 3 impedance taps.   You will also find variable input adjustments for the audio signal.  

The amplifiers are in perfect working condition and the tubes test strong and clean.  We ran the units on our workbench to its full rated power and it measured clean. 

It was also tested in our listening room for some time to ensure that what the test equipment reported translated to good quality audio. 

A few of the capacitors were also replaced that were a bit suspicious, so the units are ready for longtime reliable operation in a new home. 

These are super rare and collectible, so no lowball offers please.
