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.

It is in the audio board - trust me on this one (and it may have taken out one or more of your tubes). It is not a difficult fix but you will likely need a Tenor tech to help you.

This never ceases to amaze me. Imagine that your $10K plus amp has a problem yet the dealer and or manufacturer has not the class to respond. Only audiophiles will lay down for this treatment and make excuse after excuse.

WAKE UP.

Tenor is in trouble, a well known fact. Get used to the fact that you are most likely on your own now. Your dealer knows Tenor is in trouble, and most likely no longer carries the line yet has something "better and more resolving" to sell you. Good chance the dealer if he has a tech doesn't even want to touch the orphaned product.

Yep, where else can you blow 10K+ on an item only to find after a short time that there is no support, no help for ya, and no one will respond to your calls or email.....

Welcome to the world of the audiophile.

Best,
