Joule Electra VZN-160 mkIII Marquis

This is a pair of mono OTL amplifiers. These are some of the most beautiful sounding amps - incredible really.  But - please don't purchase these amplifiers unless you understand the speaker limitations and have researched OTL Amplifiers.  The company is no longer in business as the owner retired, but there is an engineer in New York, that services Joule equipment (https://sigsound.com/classic-product-info/joule-electra-info-page). These mono amps were upgraded to the latest model with inboard variacs prior to the company closing.  I purchased the amplifiers about a year ago and have enjoyed them immensely. I am only selling because I have built a pair of OTL mono amps myself (from scratch).  I bought these in January 2020 - I am the third owner. Here is an edited version of what the previous seller wrote in the listing: 
 *** Beautiful Output Transformerless (OTL) monoblocks Class A 

power with 160 wpc each into 8 Ohms.  I rated them in very good condition primarily because of their age otherwise I consider them to be in excellent condition.  I am the second owner.  When purchased the amps went straight to Joule Electra for the latest updates which I think was primarily in-boarding the previously out boarded power supply.  So when I received them, they were like new.

The musical qualities of detail and transparency of these amps is outstanding.... I also have several spare Russian made 6C33B tubes.  I have tube dampers for these ~$14 apiece free of charge. The fuses have also been upgraded..... Power requirement per monoblock is 500W. I also have the original manuals and shipping boxes.  One caution is that these amps run hot as you might expect. So be careful if you have small children or pets.  I will be happy to walk you through the setup of these amps.... It's not difficult but will take some time.  

You should be aware that you can't use these amps with just any speakers. Being OTL does mean that these amps will not work very well with current demanding speakers of low input impedance (lower than 4 ohms).  So please check out your speakers. ...  If you are interested please read reviews that discuss the pros and cons of these amps (http://www.audioreview.com/product/amplification/amplifiers/joule-electra/vzn-160-mk-iii-grand-marquis.html). Initial setup does take some tweaking. After that a few things should be periodically checked requiring very little time. 

I believe that Jud Barber the owner and brains behind Joule Electra equipment retired and the company no longer exists.  However, there is a person who trained with Jud who repairs Joule Electra equipment.  So there is still support for repairs if needed.  I will be happy to share this information if you purchase the amps....There is no better sound than that from an OTL amp IMHO and these are one of the best. ***

I have 8 brand new 6C33b power tubes + 2 or 3 spares that came with the amplifier.  I will include these at no additional cost other than Shipping. (These 10 or 11 tubes will require another carton). Please note buyer pays shipping AND insurance.  I will insure each amplifier for $5800.
