Just wanted to touch base in case there was anyone following this thread out of concern for their Renegade Head.
As it turns out 2 different techs one being from Egnater have both stated that they believe the buzz to be a preamp tube, and from all I have read on possible issues including in the frequently asked question section of:
http://www.eurotubes.com it sounds to more than likely be a preamp tube which will be a no biggie in the scheme of tube amps and performance concerns, and falls under routine maintenance so I am not so worried anymore.
I will not be doing the tube inspect until later next weekend around the 25th of January so for anyone waiting with bated breath be patient.
What I have done in hopes of minimizing any possible future issues, or at least in narrowing down any possibles should I need to look further or for future reference is.
1. I Star grounded my studio gear which helps to eliminate or minimize ground loops that could contribute to or create interference in the signal chain, plenty of info on the net on this if your interested in learning about it.
2. I just picked up a Monster Power Center Pro 3500 power conditioner, which I will be running all my gear through in hopes of eliminating noise and interference in the signal chain of my gear and minimize energy spikes, many people swear by this and claim their tube amps are as (quiet as a mouse) as one user noted, of course there are those that claim power conditioners are a myth that do absolutely nothing...don't care and don't want to debate it, thought I would make my own educated guess by getting one and trying it out myself, at the very least I have a single power source to power up and power down all of my gear with the push of a single button, hell that's practically worth the $260 price tag that Phil at Sweetwater was kind enough to offer me.
3. Paid a certified electrician from a very reputable company to completely inspect the power coming into our house, and do diagnostics on all the outlets and have learned that I have a designated power outlet as well as 4 - 20amp wall outlets in my studio so I now know there is plenty of power for what I need and use, so I can be rest assured its not a ground issue or anything related to our home which we just purchased and moved into at the end of October 2013.
4. I completely rewired my main guitar with new premium CTS pots and Orange drop Caps 22uf bridge, 15uf Neck, thin 26 gauge wire for minimum loading and grounded the whole circuit using star grounding and is fully shielded with copper foil through out the entire body and pickup cavity, and am waiting for my set of Seymour Duncan Antiquity humbuckers to arrive sometime around Friday which is why I am waiting to pull tubes and test, wanted to be absolutely sure I left no stone unturned and that its not a wiring issue or ground problem in the guitar, and though I am almost certain it is not, I wanted to do all of these things at one point or another anyway, so this incident just kind of pushed me to do what i have been putting off.
5. Today I opened up the back of my closed back 2 x 12 cab that I had made by Mojotone for my Renegade Head, its loaded with Celestion V30's for 16ohms and I happened to find the speaker jack very very loose, as in I turned the nut off with my fingers (could that cause any popping or scratching ?) don't know but, it sure dosn't hurt that I tightened that up.
So all in all I have done all that I can think of to eliminate the need to look outside the amp as a concern and everything I can to minimize any causes of interference that may affect my amp or gear in the future which has left me feeling a whole lot better about everything, and I am confident that once I do replace all of my tubes when ever that may be I should by all accounts and purposes have alot of years of quality studio time to look forward to.
I will post back sometime later next week to note my findings and wether or not it was necessary to change out any tubes or just clean the contacts and reseat them, Im also going to do a bias adjustment on the power tubes so I can know myself what the setting is there.
I encourage anyone new to tube amp maintenance like myself to get yourself an education online, as the info available is very informative and interesting, and will hopefully prevent me from making alot of tube amp maintenance mistakes that I already know I would have made in just handling or seating new tubes not to mention in setting the bias.
