Hello,
I have got a new Princeton 68 for a few months and I'm completely happy with it. Simple and work great at low volume, whatever the guitar you plug in. Nice. And very quite. :D

Nevertheless, I wanted to push it a bit. I plugged a guitar and turned the guitar volume to 0.
Then pushed the amp volume.

After 4/5 a hum started, becoming very noisy after that. At 8 to 10 it's like you're listening to the sea... Adding treble adds lots of noise :shock: but even with treble at 0 the noise is still there.

I really wanted to know if it is just normal or if there may be some trouble with it...

Indeed I have an "emulation" amp that is quite at every volume but it is not the same technology at all.

Thanks for the feedback.

Check your guitar first.
Amp ; try to turn volume at hight with no guitar.
You should see if it is the guitar or the amp make the hum .
Wich guitar do you use ?

It's a Les Paul. But it's exactly the same noise with no guitar plugged in.

Amp must be on warranty , can you return it at the store you bought ?

Issue might be a tube . Are they all seat well in their socket ?

Is you home have good electrical ground ?

Cell phone , PC , hallogen lamp may do some hum in the amp . Shut all these thing a check hum

Definitely a problem. Check the items mentioned above and if no relief is forthcoming, take the amp to an authorized tech. You should be able to dime it and hear nothing beyond a slight hiss.

Thanks, i'll make these checks.

I live in a French village and had to buy it from a website which will make it not so easy with the warranty. Bad news.

RaphRaph, welcome to the Forum! :mrgreen:

One thing you may want to try (and it won't void your warranty), is to spray a little contact cleaner on each tube's pins and the sockets. Work the tubes in-&-out of the sockets a few times. I like Caig Deoxit GN-5.

Good luck!

I'll do the contact thing.

I tried again today and almost change my mind :mrgreen: it's difficult to say if it is normal or not without comparing with another one.
Ok there is a hiss that is very strong at 10 with treble at max, but who play at more than 6 ? And I tried the Vox vt20 everything at max and the hum exist even if lower in fact. I was worrying too much.

As long as I cannot compare I will keep it as is. I need to try it with the band to see if it is annoying when playing loud in a real situation, not when standing just in front of it and listening to the noise.

Thanks for your advices (and welcome in France Startele52; in Paris do not miss Montmartre and La Place du Tertre in the evening to be a real tourist.)

Hiss or Hum... my english vocabulary is too poor... I would say "hiss".
In fact it does "chhhhhhh" to be read in French :)

The "place du Tertre" is just beside Montmartre, go there to eat an evening.

Hiss is more of a tube related issue. Usually white or brown (random Brownian motion) noise.

http://fr.wikipedia.org/wiki/Bruits_color%C3%A9s


Hum = more of a power supply, ground loop issue. 60Hz (mains or heater line) or 120Hz (rectified hum) sine wave noise.
