Very pleased with my Egnater Renegade head, its been going strong for just over a year, burnt one preamp tube and is just now ready for a power tube change, I have jammed almost daily for several hours (including using it as a stereo to crank out tunes using a CD player into my mixer into a Rivera RockCrusher Attenuator into the Renegade while working on other gear) so I feel like I got a great deal buying this amp.

My head came with 2 Tung Sol El34B and 2 Ruby 6l6GC power tubes and I have literally had this thing cranked at club volume attenuated down to studio level and sweet sweet power tube break up the whole time, for a grand I couldn't be happier.

Just today a Quad of Tung Sol KT66's arrived and I am waiting for those to warm up before installing them for hopefully the next year long run, I had to remove the bear trap retainers as the Tung Sol KT66's have a metal base and is said to have a part of the tube wired to the 1 pin, whether this is fact or not I cannot say but it has been widely talked about on many forums so I didnt want to risk frying my tubes by grounding them to the base and removed the bear traps, I bought the appropriate KT88/66/6550 spring retainers to replace the bear traps, but was told I dont need them if my sockets are tight and hold the tubes well, of course if I was hauling this thing around I would defiantly advise putting the spring retainers in regardless, I also made sure to bust out the denatured alcohol and dip the tube pins in hopes of keeping the contacts of the amp clean, I have run alot of different preamp tubes through this thing experimenting and the last thing I want is to be gunking up the contacts and creating problems that dont exist, and before you fire up those new power tubes make sure you turn the bias controls all the way down on both sets of tubes, you dont want to accidentally red plate your brand new tubes and have to try and sucker the vendor for new ones because you forgot that step, the manual suggest setting the bias point between 60-70mV I just set mine to about 66/67, had to go back and re-bias the first set after biasing the second set as it changed the setting once the second set came into play....Im feeling good about this quad as both sides biased easily with out big fluctuations, I was worried about the tubes being stuck in the hands of the US postal service and the freezing temps out there for the last week but these seem to be operating up to par. :)

I have tried many preamp tube brands in the various positions and have found the Tung Sol 12ax7 to be the most clear and tone full sounding for my uses, I prefer to use my clean channel for the brunt of my work as my signal chain goes: guitar into a Peterson Stomp Classic tuner into a Origin effects Cali 76 compressor into a Carl Martin Parametric EQ into an Ethos Overdrive into a Strymon Timeline delay into a Strymon Big Sky reverb into a Pigtronix Infinity looper into an Allen and Heath Zed 10 mixer (which also has my CD player running into it) using the auxiliary out goes into my Egnater Renegade head (Clean channel 1) which goes into the Rivera RockCrusher attenuator into a 2x12 16ohm Mojotone cab of Celestion Vintage 30's, I have been very happy with the harmonics and tone I can get out of my guitar, I cant imagine that spending twice as much on a head would have been better than this.

So all told after today I will be running 6 Tung Sol 12ax7 preamp tubes and a Quad of Tung Sol KT66's power tubes in this beast and am excited to hear the end result, I have come to follow the advice given to me by a previous Renegade owner who told me that chasing the preamp tube dragon was madness and he found it best to find one brand you like and just go with those, and I am now experienced enough to know he's right, swapping out several brands in various positions is madness and way to time consuming for an end result that is hardly a shade different from swap to swap, I can understand experimenting with a V1 swap on occasion but now that I own a fairly hefty box of preamp tubes (kind of addicted for a bit there) I realize the wisdom of using a single brand of tubes across the board, ....but to each his own.

For the record I did call on Bruce and his staff a few times for advice and questions and was quickly answered resolving any issue or question I had in regard to the Renegade and I found this site and RIG TALK to be very helpful in alot of things I wanted to know in regard to the Renegade and tube amps in general, I will say if your buying a tube amp it behooves you to get a tube amp education as it will save you alot of stress and money maybe even your life if your more adventurous with a screw driver than you are with the computer.

So thats Rule no #1 get and amp education, I have learned that 90% of the time its just a tube problem, meaning an easy do it yourself fix which can be narrowed down to preamp or power tubes relatively easy, and the wealth of knowledge available online is astounding, so dont be afraid to do some research yourself, and in other forums, many problems are often tube amp general more than a specific brand, learning alot of the stuff I have has taken away alot of stress and worry, its all just parts and procedures, first try this then try that, but dont panic...lol ....I know I did too...lol

Rule #2 in my book, (get a good attenuator) the tone you will experience will leave you addicted to tube amps for a lifetime, I cant even imagine using an AXE Effects without a tube amp or any other direct device from this point forward, give me some tubes and a screw driver and I will gladly tinker and maintain to get that tone only tubes truly produce, heard all the modeling crap you can have it.

Rule no #3 for me its Tung Sol preamp and power tubes all the way, built solid as a rock and they sound great, and strangely are priced very fair for a great sound I am very pleased with, the only tubes I long to try since I found Tung Sol are Genelex Gold Lions which I will get to, but for now and for the price Tung Sol cant be beat.

My Egnater Renegade has been good to me.

Hey guys just an update, these Tung Sol KT66's are Clapton's Gibson tones all the way, I biased them around 66/67 on each side and man these things along with the Tung Sol 12AX7's give you that smoking blues tone to die for in spades, my amp is smoking, lol not literally, though I had some issues early on that freaked me out, thought it was a power transformer or something, turns out after messing with my (Cough Bull Sh**) George L cables and resetting the in and output levels on my gear and man I have been jamming all night...sweet.

Those George L's are out of here just as soon as I get some more cash, Im done getting robbed of my tone every 3 weeks because one of these lame arse George L's cables is acting up, I dont want to hear sh*t about they are great and you never have problems, (Bull Sh*t) these things suck, when you least expect it and when you forget that they could be the fricken culprit, and whamo what the heck is wrong I cant put my finger on it sound and tone issue....they are out of here.

I was down for the last 2 weeks waiting on these tubes to arrive so I tore apart my guitar, cut a new nut, leveled and dressed the frets and completley overhauled the electronics for a basic Gibson 50's style wiring after getting rid of the (Volume kit BullSh*t) and removed the covers from my Seymour Duncan Antiquities and BAM! its all paying off tonight....sweet sweet tone......

I ended up contacting Bruce and calling around and scouring the net for repair issues for hours only to find that between the George L's and some pedal level issues my amp is sounding great...whew! had me sweating, 4 week back log at the local Tech shop had me ready to get my own screw driver out for a test drive, glad I didnt that couldn't have gone well...lol

Anyway I highly recommend the Tung Sol KT66's and 12AX7's for the Renegade I cant imagine any body not liking this sound.

Oh by the way Mercury Magnetics offers Output and Power transformers for the Renegade just in case anybody is thinking about upgrading, Im seriously considering... http://www.mercurymagnetics.com/pages/c ... gnater.htm
 
Wow guys you really gotta try the KT66's in the Renegade, so much deeper and clearer sounding, super sweet piercing lead tones and a deep crunch that is pretty hard to top....

Highly Recomended: a Quad of Tung Sol KT66 power tubes biased between 66/67 per side and 6 Tung Sol 12AX7's across the preamp section, money well spent, my amp sounds Bad Ass!
 
How did you come up with the bias voltage?
I am hot to drop a quad of KT66s into my TourMaster.
Have been wondering to what voltage I should bias them.

Got any sound clips to post with the KTs in place?

Hey duffman, I just went by the Renegade owners manual recommendation for tube type bias points (which for both KT66 and 6l6 sets is between 60-70mV), as its specific to the Renegade's build so I went a happy medium at 66/67mV per set ( be sure to check the bias points a few times after install though, mine changed on me slightly a few times heard they sometimes need a little time to settle in), (the Renegade uses 2 pair of power tubes, I just bought a Quad of the Tung Sol KT66 figured if they are all matched I cant get them mixed up if I change them out later), but from what I have read KT66's bias the same as 6l6's so I would go online and check your owners manual for the KT66 bias point but I have read alot and it has been said over and over if you can run 6l6's in your amp then as long as you can fit KT66's in you should have no problems running them.

Doing a fret crowning right now I will try and get a video in shortly (got a pretty nice camera with video capability I havn,t tested yet so soon enough), but just for your info, the Tung Sol's are great, find it hard to believe there is so much ridiculous flack about them on some of the TUBE SNOB forums, crap like they are not real KT66's...ridiculous junk by know it all NOS tube weirdo's as if any of theses guys are really getting cream of the crop30's, 40's, 50's and 60's tubes...silly.

So far my experience with a variety of tubes and prices is that for the buck Tung Sol''s seem to be the best bang for quality and performance going, I mean sh*t if you burn these things up in a year why drop 2 or 3 times the price for em,silly.

I considered trying JJ stuff, but to me they are a little bit raspy sounding from all the sound clips I have heard, though I may give the JJ KT88's a try, they sounded pretty good and for a nice low price.

I may go out and buy the Genalex Gold Lion KT66's though, they only run $160 for a Quad, they were my original intention on this last tube buy, but I got stuck having to pick up a few luthier files so I had to drop down my price point for the tubes and settled for the Tung Sol's, I cant say I mind, I normally use Tung Sol exclusively for my preamp section so going with the Tung Sol Kt66's wasn't a disappointment as a matter of fact Im very happy with them... excellent tone, Im just itching to see what the whole Genalex Gold Lion rave is all about, so I guess I have another power tube buy on the horizon sooner or later.

Just a note, if your an EL34 guy you may not be as stoked about the KT66's in that they are very much like a 6l6 alot cleaner but deeper sounding, for me thats the ticket.

ps: they also sound great if you like to run your CD/mp3 player through your amp in between jams.
 
Thanks for the reply.
Looking forward to hearing/watching a video of the amp with the new tubes.
I did get out my manual last night for a look see and KT's are listed with a bias voltage.
Looking forward to dropping a set of these in.

Got my replacement quad of the Tung Sol KT66's very nice, no problems with this set so far (fingers crossed).

I noticed that these sound better biased a little hot, so I set them to 70mV I set them to 66/67mV and ran them for some time but noticed they were a little grainy so after reading some online reviews and tips guys were saying that these Tung Sol KT66's sound better biased hot so I upped my bias point to 70mV and I can confirm it is true these tubes do sound better biased hot.

Yep, to all you Renegade owners, you owe it to yourself to drop a quad of Tung Sol KT66's in that badboy and set the bias hot at 70mV on both sides and ....POW! ...tone to the bone..... perfect for running pedals straight in through the clean channel. Not to mention it...but "RUSH" cranked through my amp at 2 in the morning sounds absolutely killer.
