Caevan O’Shite Posted June 15, 2008 Share Posted June 15, 2008 Say, Myles, what do you think of the higher-watt output E34LS GT for use in the Fuchs 'Lucky 7'? Any reason that I wouldn't want to run that tube in that amp? How about something similar to the 6CA7's that EVH used early on? Any suggestions? Finally- in the GT rating-# system, what would be better for getting as wide a range of clean-to-mean-to-scream tones for dynamically-responsive/touch-sensitive/guitar-volume-knob "play the amp" fingerstyle playing? A #7 or #8, a #3 or #4... ??

myles_rose Posted June 15, 2008 Author Share Posted June 15, 2008 Hi, I have another question about master volumes. Do they behave like a traditional volume control (pre-master era), or do they act more like an attentuator that reduces output? Thanks Depends on the amp as there are pre and post phase inverter masters but none of them act as an attenuator or load on the output section. Quote Myles S.

I would find a classic Siemens, Tesla, or creamy NOS tube of this sort from Mike at www.kacnostubes.com Heck ... it is only ONE tube ... might as well use a great one rather than a current production tube. Then again ... that is just my own two cents worth and personal taste and I love Andy's amp of your type and have worked a lot with these for clients. Quote Myles S.

haywired2 Posted June 17, 2008 Share Posted June 17, 2008 I should have asked you the other if you had any suggestions on a combo amp in the $400-$500 price range. I known you talk about the Line 6 on your website as being versatile. I'm mainly just looking for something I can do an occasional gig with without having to lug around tons of equipment. I tried a Carvin SX300, but it wasn't for me. Do you have any opinions on the Vox Valvetronics series. I know this is mainly a tube amp site, but if anyone would know, you would. We do mainly classic rock type stuff. Thanks again There are a lot of really nice things in your price range. It really boils down to personal preference and taste in tone and feature set. I will say that the offerings from Vox are really great. Lots of bang for the $$$, versitile, and they have a proven track record of reliability which compares favorably to amps using their type of construction in the price range. Fender and Marshall also have great offerings in this range. All these amps are easier to move around as a solid state output section has no heavy output transformer and there are no output tubes to replace and bias. They are lighter in weight by quite a bit. Hit someplace like Guitar Center where they generally have lots of these types of amps from most of the main makers all in the same place at the same time and check them out and compare. In the end it is your call. Well I got lucky. I went to my local GC, like you said, and found a $499 amp on sale for $299. I got a discount on top of that so I got a Crate VTX Series VTX200S 2 x 100W 2x12, out the door for $292. Not bad and it sounds great.

coolneelseven Posted June 20, 2008 Share Posted June 20, 2008 Hi Myles, Thanks for doing this forum. Just reading other people's questions have helped me learn things. Here's my question: There is an annoying microphonic rattle on one of the pre amp tubes on my Fender Blues Deville Reissue (4x10). The problem tube already has a foam tube stabilizer on it. I was wondering if there is a quick and easy (and cheap fix), but if not, how should I get rid of the rattle. Thanks again Quote Link to comment Share on other sites More sharing options...
myles_rose Posted June 20, 2008 Author Share Posted June 20, 2008 Slide off the foam block, pull the microphonic tube, toss it in the trash and replace with a new 12AX7. Quote Myles S.

nee Posted June 21, 2008 Share Posted June 21, 2008 Hi Myles. I've spent a pleasant couple of days reading back through this thread and learned a lot. A few years back you were talking to a fellow who had a Badcat amp and you closed by saying "If your amp is too loud, there are ways to tame that too". I have a Matchless DC30 and while it has acres of great tone, even on the 15 watt setting it's super-loud, even in a reasonably-sized venue. I prefer not to use the master volume as I want to get power amp rather than pre-amp distortion - it's the age-old thorny question of getting the amp "singing" at a reasonable level. It has fairly new JJ EL84s. Many thanks in advance. iang Quote Link to comment Share on other sites More sharing options...

Junior 1 Posted June 24, 2008 Share Posted June 24, 2008 Hi Myles, A short while ago I asked you about a sticky pot on my Melody Maker reissue. I took your suggestion and sprayed it with Deox It, but no luck. I guess I have a bad pot in spite of its age. My problem is that I don't have a receipt for the guitar because it was a gift and Gibson requires a receipt for service. I was just going to get a short shaft Gibson pot from MS and put it in myself. Is there anything special I should know before I repair it? Thank You Anthony Quote Link to comment Share on other sites More sharing options...

If you were not on the othr side of the country I would do it for you for nothing and even give you the pot for free Quote Myles S.

Windjammer Posted June 27, 2008 Share Posted June 27, 2008 Hi Myles, I have a basic question regarding my pro junior. recently it's becoming noisy, and the sound cuts out sometimes, or when it doesn't varies in volume and noise. My instinct says that it's time to change the tubes but all 4 fire up as normal or at least visually. This is my first tube amp, and have so far never changed the tubes, so just want to allay my fears that it's not something else. Thanks, Eric Quote Link to comment Share on other sites More sharing options...

Thanks for the advice Myles. I actually ended up changing all four tubes (two x GT-12AX7-R2 & 1 x GT-EL84R Duet) which I bought online and which got delivered today. Now my Pro Junior sounds so sweet.... the notes just sort of jump out at me... plus I enjoyed the process of changing the tubes, although I had a bit of trouble with the spring clamp. Thanks again!

BadLife Posted July 2, 2008 Share Posted July 2, 2008 I have a question about my Fender Vibrolux Reverb. I just had it gone over by a good amp tech I have used in the past. It sounds great but the reverb and vibrato sound noisy. This is about a 1974 vintage amp. The reverb is sort of noisy and if its turned all the way up sort of makes a feedback sound. When the vibrato is turned on it makes a slight vibrato noise even when I am not playing. The reverb/vibrato channel is now the blackface circut and the normal channel is the tweed circut. Both channels sound great and are dead quite except for the reverb/vibrato channel. It is only noisy when the reverb or vibrato are turned on. Is this normal? I usually use Marshall amps so I have little experience with Fender amps. I got the amp used so I have little experience with this amp.

I usually use Marshall amps so I have little experience with Fender amps. I got the amp used so I have little experience with this amp. Your vibrato issue is common. That is why it is foot swichable to a true off position. Left on it will also impact gain of this channel. On the reverb ... it sounds like V3 (12AT7) or V4 (12AX7) is microphonic. Swap one of these at a time out with one of the other tubes in the amp. V1 is good to swap with V4 and V6 is also a 12AT7 (it is the phase inverter) and the same tube type as V3. See if this fixes things. If so, buy a new tube for the offending position. Quote Myles S.

Mike Gug Posted July 3, 2008 Share Posted July 3, 2008 Hey Miles! On my Peavey Classic 30... I've got some noises coming from my amp. Low rumbling. The noises stop when I push the tubes deeper into the tube sockets with my fingers. This was pretty bad two years ago so I sent the chassis back to Peavey and they resoldered some joints for me. The noise was lessened, but never really went away. Now the noise is back to the point where my sound guy is complaining that he has to mute my channel when someone is speaking through the PA while my amp is on. I've increased the pressure of tension of the tube retainer clasps (is that what they are called?). That helped a little. Do I need to replace my tube sockets? How do I get rid of this problem?

Mike, These are fun amps but you need to remember they are a very high production mass produced amp and use some of the least expensive components and construction methods available. Having these kinds of problems is expected and the nature of the amp. You may want to have the sockets replaced with high quality sockets such as Belton or ceramic units and make sure all the screws are tightened as there are a lot of self tapping sheet metal screws in these amps with no nuts let alone lock washers or locking nuts on machine screws. In the end you don't want to put too much money into these. If you love the tone it might be cheaper to hit Guitar Center and just buy a new one every two or three years if you are active where the amp moves from gig to gig once a week or more. Quote Myles S.

Powerage Posted July 4, 2008 Share Posted July 4, 2008 Hi Myles, I am new to the forum but have been reading your posts for a while and find them very interesting and helpful. I have a question regarding a matched phase inverter valve. My amp is a 65 Twin Reverb re-issue project. It has a Hoffman AB763 board kit, Mercury Magnetics transformers, Torres Engineering beefed up mod kit and Tone Tubby speakers etc. I am about to replace 6L6's with Tung-Sol 5881 (#5) valves. What matched phase inverter valve would you recommend for this amp? Thanks, any advice is appreciated. Powerage Quote Link to comment Share on other sites More sharing options...

Geronimo Posted July 7, 2008 Share Posted July 7, 2008 Hi Myles, I just purchased a new Fender '64 Vibroverb Custom. I love the tone of it. Right when I got it 2 of the 12AX7's were microphonic and made the amp squeal and feedback like crazy. I went down to Guitar Center and replaced them with GT Gold tubes. The amp is still hissing when it gets really warm and popping when the volume gets louder. Would it be a good idea to replace all the stock tubes (Fender GT) with NOS? I think the output tubes are pretty good ones, right? Any suggestions on tube replacements? I am looking for blues and rock tones in the SRV territory. Thank you so much for your help. PS: Any chance to get a ride in your T-38, she's a real beauty! Quote Link to comment Share on other sites More sharing options...

If it is a vibrato channel issue it is probably v2 or v5. That T38 is long gone now but if you know somebody that would want to buy it I may be able to get in contact with the last person that had it up for sale. Quote Myles S.
