So, was just reading an interview with Metro on Red Bull. where he claims (written in 2008, but STILL...) that Kieth (JTS) "Nah, Tubby’s don’t know how to make amplifiers" and that Barracuda built em (or does still) Anyone shed any light on this? Seems odd, i know Kieth is VERY well versed in electronic design... https://daily.redbullmusicacademy.com/2018/08/mysteries-of-soundman-metro" rel="nofollow - https://daily.redbullmusicacademy.com/2018/08/mysteries-of-soundman-metro |

Geezer is obviously jealous, and has axe to grind. The End.. Anyone who knows Keith, knows he is a supreme engineer. I once heard him at Scala, play 6x Turbomax Scoops off 1x amp, he modified/re-engineered. Can safely say, I knew of no other amp in the World, at that time, that could dish out that much power, and not lose it's lunch, keeping those unruly, hard to drive drivers, in check.  ------------- Global Depopulation - Alive and Killing. |

I did think it was an odd thing. I own one of his UltraAmp (three strips of 1200w at 4R). Beautiful amps

All I know is Tubby is a Don of amplifier design and development, and Mr Eddie built fine amplifiers that were not designed to fry their output valves. ------------- Freedom of choice, choice of freedom. |

In a very old thread, it looked as if the UA6 was something Chinese called an MT1500. Almost identical pictures by service dept Steve and another forum guy. However, looks can be deceiving and the JTS amp may well have had components spec'd by Keith. A few years back I discussed the ua with Keith and was told the output transistors were no longer available. ------------- Freedom of choice, choice of freedom. |

"Think" I posted pcs of the MT1500. And IIRC, Keith said the Hitachi Output Devices he upgraded to, where no longer available, so that was the end of the UA6. A mate also had lightweight version of the UA6, and when it worked it was great, but when it blew, components not around to fix them. I'm sure Keith has now moved on to Powersoft X series, so that tells you a lot... ------------- Global Depopulation - Alive and Killing. |

I've heard a lot of people say, Inf8Mk2 did not sound nice on 1850s. When I played my 8x Oberton 1300xb loaded Scoops on Quadros 2x Voids, was different story, people amazed how smooth and round, the sound was. I would argue, Void was just too much for 1850s.. ------------- Global Depopulation - Alive and Killing. |

I've heard PD1850s in S118 Scoop sing nice on Void 8MK2. Maybe was the huge amount of wadding in the cab. But push them 1" more they can handle, all that niceness out the window. ------------- Global Depopulation - Alive and Killing. |

I wouldn't be at all surprised if K did some research on OEM and the ca series, found a company who had the best reliable QC and then speced his own upgraded components.

i have hurd wsp use naphons and pd1850s and make mince meat out the other sounds. king alpha still uses naphons with turbo max sounded much better then iration in subdub 2019 roots injection had 1850s and a naphon and sounded good ital power use pd1850s and a naphon i think they still do not sure all of the above sounded good with that combo. not sure what sounds you listen too but times have moved on this combo is a thing of the past...but just saying a point |

I owned naphon and 50s and 51s and tmax 1000 1200, 1500, fane 1500, and many other drivers. Heard all the sounds above multiple times, helped tune another roots sound at a dance also using 50s in wsp/tubbys steveb 50 scoops. Also oowned same wsp stevebs with 50s.The amp never sounded good on any of these occasions in my opinion. Its not to say there wasnt a certain level of spl. But it didnt sound gd to my ears. The amps never reproduced a 'nice' sound. Everybody has different ears and different requirements for their systems at the end of the day. For me the amp could not fullfill mine and i couldnt wit to sell it

Yes bro, although i've distanced myself from the other member of ballistic and am doing my own thing now. I had 10 stevebs altogether, and over 30 scoops including other designs. For me the amp just didnt cut it. On the mini scoops it coulldnt play them at all. Tight chamber cabs was better for it but again not at all what i wanted. Every other amp i used yielded better results, even smps which everyone knows i prefer big heavy torroidals on my subs. Matrix 7k, pl380, crown xls5000, ca18, inf8 played all the notes with good quality and tone with spl. The naphon just didnt play all the notes and has a type of noisey harsh sound. The sound i sold mine to used it on 50s in different scoops eminence wardrobe style wide cabs which play the notes well but again with that amp it just wasnt there and had that noisey sound to it.

This article is a good read and if you view it in the context of an old school engineer I understand where he's coming from, with a background in valve constructed devices as well as transistor he was well grounded in electronics. I dont think but know that some of Jah Tubbys early pre's and amps were down compared to todays standards, and that would be the same for Links and thats to do with a better understanding now of electronics theory, the application of linkwitz-riley vs Butterworth principles, phase and the availability of better components. It would be unwise to think that JTubbys has not moved with the times. 'Metro' would be in his early 80's now and in his time everyone one else would have taken credit for something they claimed or didn't do. ------------- Soundbite |

So, according to Kieth, Metro isn't correct. Kieth learnt how to build on his own.

I heard he had X8 on sub driving Redeyes last time he played Hytal Bosrah, and they had Bridged CA18s. Also was told by electronic engineer who was there, Bosrah sounded extremely heavy.

It's a while ago now, but I sat with Keith in his studio and talked at some length about lightweight Tec. At the time it would have greatly suprised me if he had begun to switch to smps. We talked about long term power Vs burst ratings. He, at that time was saying smps, good for transients but for bass, not really up to the job. Maybe that has changed, but at that time (still when powersoft were being raved about), he wasn't saying they were capable enough. It's also when I learnt Ua series amps had transistors that couldn't be replaced.

| He certainly had 2 1u class d looking lightweights visible at the top of the rack last time I saw Tubbys (2019), the back plates don't look like powersoft though. Maybe for mid range if the transient response is favoured.

I think that's a good point. A brief look at someone's rack doesn't tell you what is driving what. A longer look watching signal LEDs tells stories but other than that, it's conjecture. Which apparently is what certain forums rely on....... ------------- Freedom of choice, choice of freedom. |

i would imagine Keith being old skool that x8 is buried in that old school amp case on the bottom old school reggae style smoke and mirrors its great , i am just about to re case my bass amp with crazy cutom led vu meters on and polished ali front just for A NODD to the old skool way of reggae system , can see in few old vids 1u lightweights on tops and crest pro series on mids but this was years ago( i see there still there now but just because there there don't mean there used ,being light also no effort to leave in racks , and yes the night with hyal was heavy, best I have heard bush sound ever on the 2 crest in bridge it was scary great stuff :)

I've not heard any Dub set using double boxes, that comes close to WSP. In fact, would still say, he is the No1 UK Dub sound right now, with Aba and Iration not far off.

agreed!! So, if i was thinking about a new Tubbys amp, which one would be recommended?
As i hear a few on here saying the UA series have no spares now... would they still be good to purchase? Or is the older Annihalator MegaAmp series still worth a look too? |
