JOULE-ELECTRA VZN-100MKV OTL Power Amplifiers - $5,750 PLUS SHIPPING

***Scroll down to read full details/description below!!!***



This is a beautiful pair of Joule-Electra VZN-100MKV 100W OTL Tube Power amps for sale. This pair of amps is approximately 12 years old and during the past two years I have done a number of upgrades/mods (and unfortunately some repairs due to shipping damage on one of the amps - see details below) to these amps. So, if you are seriously interested in these amps, I have some detailed info here for you in the following notes about this pair of amps that you need to read:

 1) These amplifiers a utilize a Class A circltron OTL amplifier topology. Translation: no output transformers for exceptionally wide bandwidth and tube purity tonality AND HEAT! Class A tube OTL power is not efficient and these amps will pump around 900W of heat into your room. A dedicated circuit for your system when using these amps is a good idea - they will draw around 8 amps from the wall.

2) While the amplifiers are monoblocks, they both plug (via umbilical cables) into the square power supply with the knob on top (this is called the Variac unit) which forms part of the power supply for both amplifiers. Only ONE AC power cord goes from the Variac Unit to your wall outlet (or power conditioner). The umbilical cables attached to the Variac Unit allow the amps to be placed around 10ft apart at most.

3) This pair of amplifiers did NOT arrive here in the condition you see here. Their owner made a mistake in packaging and one of the amplifiers received some damage to the amplifier's enclosure. There was no electrical damage to the amp, but a bunch of tubes got busted. The damage to the enclosure was repaired by me and then I had BOTH enclosures professionally re-painted by a gent who knows what he is doing who did a great job. Any waviness, chips, or cracks in the finish are gone - these amps look better than when they were new. Most ALL of the tubes have been replaced, remaining original tubes where only used if in excellent condition.

4) These amps have a unique modification which I made to them two years ago when they where here for some service. The variac in the external Variac power enclosure was replaced with a larger capacity unit and fully re-wired. The variac provides the raw AC for the roughly filtered DC power arrangement for the 6C33 (output tubes) filaments (and the 6C33 plate power supplies). The 6C33 tube filaments were switched to AC power arrangement for the 6c33 tube filament string. The tube filament string in these amps draws a large amount of power through the Variac, so by switching to AC power on the output tube filaments the amount of mechanical (vibration) noise from the Variac unit is significantly reduced with NO cost to the electrical noise these amplifiers generate at their outputs (i.e through your speakers).

5) This brings me to my last note. Joule-Electra OTLs are NOT very quiet or noise free. On a typical 87db efficient speaker, you WILL hear some amount of buzz/hum/hiss (which will vary depending on the amps feedback setting you are using with your speakers) from your speakers when you are standing right next to your speakers. These amps are not for folks with high efficiency (i.e mid 90's or higher) speakers in general. Having said that, I and many of my customers over the past 20+ years have very happily used VZN-100s with Merlin VSMs speakers (90 dB efficiency).

The amp will come with a spare 6C33 tube. The small tube compliment in each amp is a pair of 6922/ 6DJ8, one 5751 (usually NOS JAN USA), and two NOS 6350s. Post repair, I have done extensive testing and monitoring of the amps operation (this is over several 4 to 6 hour sessions with the amps) to ensure they are working properly and stably.

These amps retailed for about $18,000 when new with the MusicWood enclosure option. These amps can be yours for just $5,750 plus shipping. I have factory packaging (plastic crates) for the amp chassis and extensive experience in SAFELY packaging and shipping these amps.
