RA100 head. New Amp Day. Notice hiss/static

[jetdriver]

I just got a Royal Atlantic head today. Love it, but I am getting a fair amount of hiss/static at all times regardless of channel, mode, reverb, volume etc. it isn't a steady white noise, but more like waves and crackling. Volume pedal in the loop wont quiet it eiether. Maybe a tube? Any thoughts?

The reverb can be a bit noisey at low volume, but that is not an issue at higher volume.

Does the noise stop if you turn the master all the way down ? If not then it will likely be an issue with one of the power tubes or the driver tube and your shop should be able to do a change out for you under warranty.

When mine first arrived one of the internal reverb connections had come loose. It caused some noise that was fixed when I re soldered

Hey guys. This noise happens at any volume, even with the reverb bypassed. Although, it does seem like I don't get any reverb until its up past noon, then I get fair amount.

sounds like it might be a preamp tube going bad...
After you trouble shoot it keep us posted when you fix it.
swap one tube out at a time.For power tubes MAKE SURE IT'S MATCHED!!!
I'm sure you already know this.

Thanks. I'll be sure to post the fix.

Stuck traveling for work. Won't get to it for another 3 weeks. Ugh! Hahaha

IS your amp fixed?

 

[jetdriver]

I'm out of town on business thru the end of the month, so I haven't gotten to it yet. I'm
sure it's a simple affair.

Probably totally trashed. I will take it off your hands for $800 as is.

Deal! Just send me the cash first. :lol:

I can probably beat $800, I have this Nigerian thing that's about to come through huge for me, I just sent them my bank acc't number and it's a done deal.

Also interested to hear about the fix when you get to it.

I'm happy to report that the amp is fixed. It appears to have been a temperamental tube. I took it back to Sweetwater and they couldn't duplicate the problem. They said that is sometimes the way with brand new tubes. Once I got it back home and played it, it was still dead quiet. They gave me a spare 12AX7 just in case, but it appears that the issue has sorted itself out. Great amp!
