I have problem with my Tenor150 - advices welcome

i am experiencing a random waving little high frequency noise in the tweeter of one of my JBL K2S9800, that i tend to believe, comes from my Tenor 150.
Intensity is variable and noise is not always present (usually not there at start and tend to be less present after 4/5 hours).
It is not a uhm (wich is also slightly present).
It does disappear when amp is in mute mode but remains kick and fitting when the amp is in stand alone mode (with no connection to the pre-amp).
Noise has increased in the last days.
When i change the plug orientation noise is migrating from one channel to the other.
Voltage is a stable 240v (with no ground due to the age of the electrical installation)

Thks beforehands for your insights.

I did not get answers from Tenor to the mails sent in the last two months and i understand they have other priorities at the moment but i would really like to have this problem fixed.

Tish, tish, unreliable products are exciting mainstays of the high end. When the high end was born there were a passel of marvelous, but unreliable, products right there in the delivery room. Futterman OTL amps, Beveridge and Janzen speakers, Andy Rappaport amps, Dyna MKVIs, Dayton-Wright, Hill Plasmatronics, the list could go on for pages. It's just like owning a British sports car, relax, revel in the imperfection. It was made by the hand of man. It can be fixed by the hand of man. You have a rare and beautiful amp. What's the big deal about a little upkeep? Not everyone will appreciate it. Let the other dudes own Sony and Honda.

There's a reason why every company Viridian mentioned (including the British sport car makers) are out of business. Apparently the vast majority of people want something that works reliably when they pay their hard earned money. Could it be those other dudes own a Lexus and Mark Levinson.

Sorry you have a problem Mqg30, its a real drag when the rig goes down - hope you can figure it out.

BS like this is why I now will only buy from large companies like CJ, MAC, Meridian etc.....no more esoteric startups, latest and greatest, blah blah. It's hard enough getting service from reputable companies much less short timers not even willing to answer mails!

The British sports car makers out of business, perish the thought. Jaguar is doing quite well, though it has a new owner, as does Levinson, for that matter. Many of the older models from these sports car companies bring many times their original sale price; I can't think of any Lexus that does. But yes, most people want reliable, well built products. Like Sony, like Bose. In our modern world many do not have the time to spend on upkeep. For them there are products like Mark Levinson that work every day. A manufacturer of tube gear said it very well once. Solid state is like a stuffed dog, no maintenance required. Tubes are like a real dog, it pisses on the floor from time to time and you have to walk it quite regularly.

Obviously Viridian can afford $20K amps that break with no support. Surely it must be nice to live in your world, where $10-$20K audiophile pieces that have no support or service availability are a minor thing.

I must have to work harder for my money, and value to me is an item that has support, and a ready and available service path.

Tish tish, my junky Levinson and Aerial, Classe pieces work every day.

Best,

Paul :-)
