new guy amp question..... i was playing a maz 38 and vht ab'd when i started getting a strange sound. after ruling out cords and guitars i narrowed it down to the maz 38 nr being played thru a z best..... when i play the strings fretted it sounds like i am playing a 12 string. i took pedals out of loop strait to amp... was wondering if that what it sound like when a tube goes microphonic or just bad...... any suggestions? talked to the dr and a course of action is underway..... will let you know how it turns out :] jb This can be a few things ... start by taking a known good 12AX7 and trying it in the other positions, one at a time. Could be a filter cap if you are getting harmonic overtones but this is hard to confirm from your description. Try the 12AX7 deal first.

Myles, I have to replace some tubes on my Ghia. What is your recommended tube complement for the Ghia. I apologize if you have answered this before. Thanks. John

Myles, I have to replace some tubes on my Ghia. What is your recommended tube complement for the Ghia. I apologize if you have answered this before. Thanks. John John, This is really personal preference but .... On output tubes ... EL84S in a 5 or 6 rating. V2 ... I use an RCA Command Series 5751. I also have some GEs that I use at times too. They came from Mike at www.kcanostubes.comIn V1 I have a Telefunken. Yes ... a real NOS one .... it was a gift and I typically dislike these in almost every amp on the planet but love it in my Carmen Ghia. If you can find a good Ei long smooth plate 12AX7/7025/ECC83 those are virtually the same as the long smooth plate Telefunken in the Ghia. But ... this is personal taste and having 3-6 tubes for V1 with a Ghia makes a lot of sense as they can be swapped and played with as the Carmen Ghia is so responsive to V1 tube changes. A 12BH7 for V2 is nice to have on hand as it turns the amp into a cool little jazz monster in ten seconds. Grab a good NOS 5Y3 rectifier if you still have the stock one in place and keep the stock one as a spare. With a good NOS rectifier you will probably never need the spare but it is always a good idea to have a spare rectifier and set of output tubes if you gig without a backup amp.

Myles - DC here!
I did post this question in the tubes section first - in the thread about Shuagang KT66 tubes. I'll repost it here - I figured you check this thread more often. ( I deleted the original post )
You said in February that jj KT77 was a killer tube. You were going to put it into a RXES amp I think for testing. Would this tube work in a Route66?
Cheers: Dixiechicken

Cheers: Dixiechicken It will not work in an RxES ... if I said I was going to try it in there I made a big mistake. The RxES is an EL84 amp not an EL34 amp. It will not work in the Route 66 .... as it is not a part of the KT-66 / 6L6 family. I did try it in an SRZ-65 and it was so good that Carl Verheyen now uses that tube in his own SRZ-65s both in the USA and his Europe rig. The SRZ-65 is the foundation of his rig which includes the SRZ-65, Marshall Plexi 100 watter, Vox AC-30 and Fender BF Twin Reverb. The SRZ-65 is the only piece of non vintage gear in his rig by the way and in the GT artist spotlight it is the only amp shown in the advertisment that is not a vintage piece of gear as well if you don't count my own GT Solo Single that was used on a few cuts of his CD that came out in July 2007. The GT amp is not a part of his live rig but is used at times in the studio. The burgundy tolex amp where you can see the back is my own amp that I designed for use on a track or two on the CD as well for very specific purposes. The big version is at www.groovetubes.com/assets/1769_gt_verheyen_large.jpg

Myles, your avatar is doing funny things to me! ;D It's 2:57am here and that's the LAST thing I need to see before bed! ;D Sorry! Here she is in more clothes: and here she is with Chad Weaver (Brad Paisley). Maybe looking at Chad will put you to sleep A little secret that Chad knows that you can't see in the photo .... there is a Marshall JTM-45 half stack in the bookshelf behind the chair that cannot be seen here and behind the chair is a Fender Tone-Master with it's cab. I pride myself on being able to hide amps in my house What is not a secret to most of the folks that know me is that I am a guy that can focus on the technical aspects of things ... the specs ... the numbers. For the the technical stuff on Anna go here - www.guitaramplifierblueprinting.com/images/aeannacm.jpg1.jpg I did not post this as a picture as this forum is open to folks of all ages and I do not want to offend anybody by mistake. I would not go to the link before trying to go to sleep.

Hello Myles.
I recently received my new Galaxie from FatSound. I love everything about. I wanated to ask what the pentode/triode switch is on the back? I have switched on both sides and don't notice a difference. Am I suppose to or is it for the inner power usage or something?
Thanks Myles, Bill (bilbal)

Hello Myles. I recently received my new Galaxie from FatSound. I love everything about. I wanated to ask what the pentode/triode switch is on the back? I have switched on both sides and don't notice a difference. Am I suppose to or is it for the inner power usage or something? Thanks Myles, Bill (bilbal) Bill, A Pentode/Triode switch will change the way the output tubes are operated. A pentode has five elements but if you remove two of them from the circuit it then is a three element triode. In triode the amp will develop less power maybe about 25% less or so, and have a more classic output response. The grand low powered single ended hifi amps that use tubes such as the great 300B (which is a triode) are one place where this is still quite common. Think of triode=vintage and pentode=modern in another sense. This is a very cool feature and when the amp is pushed in triode mode you may find the tone in the pushed clean settings very fifties or late fourties in nature. From the Z site itself: The Galaxie is a channel switching (via footswitch) amp that combines classic tweed clean tones and smooth modern drive sounds. The clean channel nails the sweet swirling sound of classic tweed amps that have become the foundation of electric guitar tone. The drive channel is the result of Dr Z’s 20 years of design experience. You’ll find it has excellent sustain and a rich open sound with plenty of gain on tap for today’s needs. The output transformer is made by the venerable Triad company and is to the original spec found in classic tweed amps like the Super, Pro, and low powered Twin. Great care was taken to accurately reproduce this transformer. Dr Z is very excited to use the Triad transformer in this design. The preamp consists of three 12AX7s coupled to a dual 6L6 output section and rectified by a 5U4. The Galaxie features a pentode/triode switch on the rear of the amp. This will enable 40 watts in pentode setting and 30 watts in triode. The sweet big bottled sounds of the Galaxie are at your command. The Galaxie is set to explore!

Thanks Myles - I appreciate your time as I'm sure we all do. Take care, Bill (bilbal) Edit: You are right BTW, seeing Chad definitely cooled me down before bedtime. That Anna is gorgeous, hot, smoking, etc... any picture of her is fine but as taswegian said, just not before bed. It's too depressing and makes things "uncomfortable" to say the least. No offense Chad!!! ;D Bill none taken. although i'm not sure how to take knowing that i 'cooled you down' and that i'm the last thought you had before going to sleep. i know who and what i think about when i lay down at night and you just saw a picture of her. you need a hobby, brother! : )

Myles, On your blueprinting site, in your review of the KT-45 you claim it to be the ideal hard rock amp for clean sounds and using pedals.
I have a Route 66 and was wondering whether perhaps trying a SS rectifier or some other tweaks might make the amp more like the KT and remain a bit more clean for use with my pedals. Going out to find a KT in a used environment is an expensive proposition if the Route could be tweaked a bit to perform similarly (granted at slightly lower wattage)
Thanks

Going out to find a KT in a used environment is an expensive proposition if the Route could be tweaked a bit to perform similarly (granted at slightly lower wattage) Thanks The Route 66 and KT-45 are very different amps. They may look the same from everything other than the output tubes but it is much more when it comes to the way things interact. The KT-45 is a unique beast as it is an EL34 amp yet can summon up big clean tones that have a lot of the 6L6 character. The amp has been used in more "Fender" roles that I can count at this point and once it is cranked it reminds me of the great cranked tones of a great Selmer or Vox AC-50. I think the KT-45 is going to be one of those amps that 10 years down the road will resurface as the SRZ-65 did recently. It is an amp that many never tried and thus realized the magic of the beast.

my SRZ65 LE is way too bright. What would be a better pre amp choice for V1? GT 12ax7m or the 12ax7r2. I usually play with my gain at 1 to 2 oclock and my master at 11.
Thanks myles

Myles...
I find my Maz Jr NR to be a bit too bright and has too much bite at times... Even with the cut at 9:00 or less. I currently have the stock Svetlana in V1. Is there a different tube I could use to darken the amp a bit?

I do this for the folks on this forum and nowhere else unless you are one of my GAB clients. Ah well I had you do that with my EL84's... I just wasn't sure if there was much to do with one tube... I guess just pick out a winner. Thanks Myles, I will definitely do this in the future.
