Need help with an issue on brand new Silver Jubilee

[musiquedereve]

I just purchased a Silver Jubilee 2555x 100W last week and it arrived a couple of days ago and now that it is the weekend, I finally plugged into it (I plugged the guitar straight in to test it out first without going through my pedalboard)

I am running it into a Dr. Z CAZ-45 cabinet rated at 120W and 8Ω with the Silver Jubilee rocker switch set to High Output (but I have tried as well on Low Output)

In order to get any volume at all I have to turn the Master volume about halfway when using the rhythm channel and, on the lead channel, I have to turn the Lead Master to 10 with the Master halfway to get any usable volume -- and even then, it sounds very thin

My Roland JC-22 puts out more volume than this

Anyone else experience this?

Do you have any spare tubes, put a known good tube in each socket one at a time until you find the bad tube. This is my best guess...

Just the preamp tubes?

OK well, I left the amp on standby during the time it took me to post this and call Sweetwater tech support and, naturally, everything worked jsut fine -- perhaps, since it was the first time I was turning the amp on, the tubes needed some time to warm up

But, it is working properly now (however, it will take me some time to get used to it as even on the High Output setting, the only way I can get a truly clean guitar sound is by having the gain at 1 and turning the Master volume to about 4 -- although, this might be how it was designed to work)

Is it normal that, in order to get a truly clean sound, I have to leave the Rhythm channel gain at 1 and set the Master volume at 4-5? Anything above 1 on the Gain and the amp starts to breakup

To The Forum
I am not sure if the gain is on 0 you will get no sound , so that may be the issue you are having, an normal ??
I am no tech , and I have zero experience with a Jube.

Cheers

If you’re on the rhythm channel make sure the rhythm clip is off.Mine doesn’t start to break up on the clean channel until 7 on the input gain.I’m even using low watt greenback Celestions.Are you using low,medium or high output pickups?

I agree with above, should be clean with the clip off to gain of over 5. No effects in loop or anythung?,
Also, the volume pot taper is different from any amp I have used. They don't really push like crazy till after 5 on output volume. You cannot compare numbers on dials on different amps and expect the same results.

Yes mod/time based effects in the loop

Check if they have level controls? Or at least try it with them out of loop and see if volume changes at all.
Clip is off and still distortion on clean channel?
