I play on a av with v30's and it sounds OK. I have a TS driving the front and a Hotplate cutting some of the volume. Here's my issue. I'l be happy one day and completely frustrated another. The distortion is not where I want it to be. Im thinking of getting new tubes.

I play hard rock-psychobilly-metal-punk. What are my tube options?? Jan 15, 2. Uninspiring is the word I would use. I got to play it for the first time yesterday for a couple of hours - with a continuous smile on my face.

A sweeter break-up comes at the lower volume and it gives me more of a '70s classic rock feel. Very happy with the change. Jan 15, 3. Messages: 4, I like el 34's I'd get a dual FS level Ho attenuator and get those power tubes and the tranny cranked up. That's just me. Jan 16, 4. Messages: 1, Power tube breakup is NOT tight. I have also never liked the lead tone of anwithout significant boosting.

What MV setting are you generally using?

This may not give you the gain or sustain you are looking for, so you may need to experiment with pedals to augment the amp's own gain. Ultimately, you may be better suited to a 4 gain-stage amp. There is a definate limit to the ear-friendly gain you can get out of 3 gain stages. Jan 16, 5. In my experience with 50W amps, the s other than the old GEs sound terrible.

I tried the Cs after my GEs went tits up and it was not even close to the same amp. I switched out to EL34s. I was satisfied but not overwhelmed and I didn't think it was as cool as the old sound.

I now have my amp fitted with 6V6s and I like it.Log in or Sign up. Steve Hoffman Music Forums. Location: Woodland Hills, CA. I'm going to retube my VTL monoblock amplifiers soon. I currently use a set of SED tubes "winged C" and am happy with the sound. I do recall reading somewhere that KT88's may be a better choice particularly Genalux. The Audiogon discussions go back and forth in opinions of the tube types. I'll call VTL after the holidays when they are open again for their suggestion, but has anyone here used both tube types?

Any preference? Location: Boston MA. My CAT mono blocks were designed to use tubes. I use the winged C s too. They sound better than KT88s in my amps. I suppose it depends on the design of your amplifier. TullmanDec 25, Thanks for the info Tullman. Location: Overland Park, KS.

General rule is that the KT88 goes anywhere a will and usually the reverse as well, but the 88 was the more highly rated tube.

It has IIRC a higher permissible plate dissipation and higher voltage ratings, but in practice they are pretty close. I would definitely check with the factory as they may have had specific reasons to specify one or the other.Apr 18, 1. Feb 11, Hi all, I saw that some tube company for ex. Are they similar or totally different? If yes, why? If no, why? Which are the sound differences? Apr 18, 2. Sep 7, Chicago. I believe KTs like a higher or are rated for a higher plate voltage than the s.

IIRC, there was a sticker on the chassis warning against using s Apr 18, 3. The Svetlana's are especially nice in guitar amps, because of their breakup characteristics, but the GE A's are widely recognized to be the tube of choice for bass amps including SVT's. For instance they're just about the only tube that'll work in a Fender PS or PS, 'cause of the extreme electronic conditions in those amps. Anyway, one of the big sonic differences is that the KT tubes break up "roughly", they're not really good for guitar amps or bass amps.

They're good for hi-fi amps though, where breakup is "never" supposed to happen.

Don't get the new Svetlana tubes distributed by New Sensor, they suck. The Sovtek's suck too, they're boomy and not at all pleasing to the ear or rather, to "my" ear. Who knows, they might even be the same tube by now Sovtek and Svetlana. Apr 19, 4.

Dec 15, Airdrie, Alberta. I found the opposite with Svetlana versus Sovtek 's. I found that the Sovtek WE's have more of a midrange growl to them and have a nice natural compression when pushed hard. The New Sensor Svetlana is very similar to the Sovtek same factory? But my all time favorite would be the GE A which has all the midrange and bass you would ever need in a vintage svt and should last much longer.

Marshall also got into the action a few years later when they released the watt Marshall Major amplifiers. Today, many high-end audio tube amp manufacturers still rely on the KT88 or one of its variants KT90 and KT for their current production tube amplifiers. And this just scratches the surface.

Since he started Eurotubes in we have had the unique opportunity to listen to and play hundreds of different amps. During the first few years we worked with local players here in the studio one-on-one to achieve the best results for each. This gave us the opportunity to play, and more importantly listen, to hundreds of different amps. Thousands of hours were spent trying different combinations of preamp tubes and power tubes to better understand their characteristics and tonal differences, and we continue to do this today.

Before we get into methods, reviews and brands we would like to answer some of you who have asked us about the new production Telefunken tubes. Most players who know us understand that we have a very tight relationship with JJ Electronic.

6550 vs. KT88 Power Tubes

In fact JJ verified that Telefunken is not even a customer of JJ Electronic and said they must be getting them from another dealer! So, you will not find reference on this page to the new Telefunken tubes because they are in fact JJ Electronic tubes.

Continuing on, we quickly learned that the method most people used to compare tubes, which is to set the tone controls to one place and leave them for the entire test was inadequate. This procedure does not allow you to get acquainted with the capabilities of the tubes. Some tubes get sweet when treble is dialed in and some get very piercing. The following opinions reflect our opinions and the opinions of the vast majority of our customers, you can find well over a thousand customer reviews here.

Below is a list of the most common power and pre-amp tubes. A good way to describe the tone in one word would be to call it "cardboard". They make your amp sound like a big Wheaties box.

The low end is flabby and only gets worse as more lows are dialed in. The highs are piercing and brittle. These tubes are just flat and lifeless sounding without much harmonic content. When over driven they get real grainy and the breakup transition is quick and not smooth. Sovtek EL84M: This tube has the same tonal characteristics as the standard Sovtek EL84 and is even more lifeless and less touch responsive.By eth2April 19, in Talkin' Tubes.

Any thoughts on the sound difference between the KT77 and KT88? Why 80w to much power that you want to drop to 50W Sent from my iPhone using Tapatalk.

Looking for help to choose KT88 tube

It isn't about the power. The VRDs are driving khorns. Is there a difference in sound? I don't own a VRD. I listen to classical music and opera. I own more than 2 dozen tube amps, in 5 systems.

Only you can decide which output tube you like with your music, your amp, your speakers, in your room. With that said, if you want to hear a difference in sound quality, I suggest 6L6GC. Readily available on eBay. Whatever you decide, I suggest buying a tested, matched quad. IME, completely ignore any suggestion that "more output power is better".

In an average size room, with any reasonable volume level, you could drive your KHorns with a single-ended amp delivering 8wpc. Or possibly less. Bottom line. That's my 2 cents. Hope this helps. The tube in the preamp will set the stage on the warmth and secondary harmonics from the power tube.Quick links. Username: Password: Remember me? Please login or register an account.

Board index Hardware Amplifiers and Loudspeakers. Are and KT88 interchangeable? Well, the title sums my doubts up about this. Although being well-known that and KT88 tubes have similar electrical behaviour and the pins are compatible in the sockets, I am not totally sure if they are interchangeable in a tube amplifier.

I mean, could be any problem in the amp issues, damages, breakdowns, My doubts come because a person told me that it was necessary to change a resistor in order to use the 's instead the KT A very good friend of mine, DIYer, says that no further changes are needed. What's your opinion in your own experience? Re: Are and KT88 interchangeable?

Its called "One-up-man-ship". My amplifier will takeKT88, and KT90's. There are subtle differences in the spec's so that each manufacturer can say that their tube is better than the others. To you, difference is what you perceive the sound difference to be to you ears. There is still another tube that can be used by some amplifiers that can handle the increased heater size and currant draw on the power transformer and that is the KT It is a recent addition to the lineup and is designed to handle higher voltages to produce higher wattage out.

And for those in the wattage race the final and newest addition to the lineup is the KT Which is out of our league unless you have an amplifier specifically designed for this size tube. Well, I own a tube amp originally with KT Later I changed them for The y sound different. More punch with KT88 and more elegant sound with I listen to jazz mainly so is my favourite to my ears.

But the guy who told me that it was better to change a resistor into the amp in order it could work properly using is an engineer of a well-known european brand. So this is the reason for my question. Anyway I am now using and I don't feel anything special in the amp. These are the tubes that take the signal from the preamp and process the signal before sending it to the power tubes.

I belong to a forum devoted to tube gear and all of the members advocate "tube rolling" of the driver tubes to facilitate the most change in the sound quality. Power tubes do make subtle changes, however according to those addicted to tubes say that the driver tubes make the biggest change in sound.

Anything that changes the operating parameters will potentially change the sound. Tubes have a huge amount of variation even in production batches.

For some circuit designs this is a problem, for some its not critical.
