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.

Hopefully, his wallet or checkbook isn't (won't be) hurting.

Hello Metralla:

In reality I can certainly feel Mqg30's pain. However.....

How long as audiophiles will we bury our heads in the sand?

I'm all for the small manufacturer bringing out cutting-edge goods, and those who buy them. The reality is if anything happens to the small outfit the usual scenario is you are on your own. Perhaps I'm the only one who feels that morally the manufacturer need be available for repair on an item that may cost more than a decent used car?

The ideal ending would be that someone with experience in the repair of Tenor's product step up to the plate here and offer the man some help. We'll see if indeed this happens.

I have friends with boutique audio orphans that no one will touch for repair. Nothing like a $10,000 doorstop.

Knowledge is power. Be aware going in with any boutique piece that you may well be left hanging. That's my point.

AFAIC, it isn't right.

Best,

Paul :-)

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.
