German Based Bulldog Amplification Approves TubeSync

Friday, June 11th, 2010

Bulldog Amplification builds handcrafted tube amps in Germany to meet  the ever demanding needs of musicians in terms of tone and reliability. Years of experience in repairing and modifying tube amps has lead to an exclusive line of guitar amplifiers. These instruments are built to produce the best possible tone. Most of today’s amps offer many different sounds and functions, but the guitar signal has to pass through various paths of electronic circuitry until it reaches the speaker, consequently the tone is weakened. Tone and bullet proof reliability are the most important things for Bulldog Amplification and that’s why Bulldog is delighted to announce that TubeSync will become standard within their The Jack 66, Jack 18, Black Bert 1, and Den Lachs amplifier models.

‘’ Robust, bomb proof reliability, with enhanced functionality and perfect tone is what we want’’ – says Ingo Bührmann from Bulldog Amplification. Ingo goes on to say…

‘’Cheap poorly designed products from China are fast becoming unacceptable to guitar players especially within Germany, where high quality engineering is embedded within our culture’’ You would buy a car if the drive was terrible and it broke down when you needed it the most, well would you? ‘’ I believe the same philosophy applies to guitar amplifiers, high performance and reliability is paramount’’.

Bulldog Amps are currently used by a number of high profile bands such as the massively popular German band Guano Apes and Livingston. Bulldog amps with TubeSync will soon be appearing on a stage near you!

Hiwatt Amplify Their Success With TubeSync

Thursday, April 1st, 2010

IT TAKES more than sex, drugs and rock ‘n’ roll to make a guitarist sound great. John Hill meets North East amplifier makers at the cutting edge of technology.


Hiwatt & TubeSync

ANDY Fallon and Colin Arrowsmith are not guit- arists. Their affair with the valve amplifier isn’t born of a youth spent practising solos or arguing over kit specifications next to the counter of their local guitar store.

In fact, Andy’s experience lies in automotive and military engineering, while Colin is an expert in microelectronics.

However, their contribution to a piece of kit beloved of the White Stripes, The Who and Black Sabbath has attracted the attention of major international amp-makers.

Andy and Colin are co-founders of KBO Dynamics, a Consett company created to market technology designed to improve audio and guitar amplification.

They are the men behind TubeSync, a “tube management system” which monitors the performance of valve amplifiers to avoid meltdowns while maintaining sound.

The product won the innovation award in the Durham and Wearside heat of the nebusinessawards 2009, run by The Journal and Evening Gazette.

KBO co-founder Andy said: “We were looking for a niche market. Neither of us plays the guitar, but we did a lot of brainstorming.

“Colin worked with microelectronics, but he’s also an expert with valve technology. We realised very quickly that the biggest application for valves was inside guitar amps.”

The valve amp isn’t exactly a rapidly advancing technological product. The technology was developed between the world wars and uses a series of vacuum tubes to regulate a signal. It was present in items from TVs to radios, but fell out of favour in the 70s.

The resurgence of such equipment has been prompted by high-end users in the audio and guitar amp market, who praise its natural sound.

Andy said: “There’s a warmer, more rounded tone to it. Anyone who’s serious about playing a guitar would only use a valve amp.”

When they developed TubeSync, the pair didn’t set out to change the sound. Instead, they set their sights on the downside, the problems that plague valve amp users looking for that special sound.

He said: “The closest you can compare it to is an engine management system on a car. It’s like having a maintenance technician looking after your amp 24/7 without you noticing it. It’s continuously monitoring the circuit, looking for faults.

“We got a market research report from Think M in Newcastle. It conducted a series of live interviews with OEM companies and guitarists.

“We looked at the problems people were talking about, but we didn’t change the sound.

“It can detect faults. It can disconnect a pair of valves if it finds one is faulty. You normally have to buy valves in matched pairs and you need to take the amp to a technician to tweak it, but with TubeSync you only need to buy one valve if one fails and it can tweak the system for you.

“One faulty valve can blow up the output transformer. TubeSync can detect this and prevent catastrophic damage.”

KBO had support from a number of North East backers. It won £90,000 from NorthStar Equity Investors’ Proof of Concept fund, developed its prototype with help from Business Link and got £20,000 from the North East England Investment Centre. The process was then advanced by a grant of £20,000 from One North East.

In all, Andy estimates the product has taken 18 months and around £200,000 to develop.

He said: “We built and developed it from the bottom up. We tried to use components that were available in the marketplace and we created our own unique algorithm.

“We don’t think there’s a similar product to this on the market and we’re hoping to receive a patent in the next couple of months.”

Right now, KBO is on the hunt for buyers. The team has just returned from the international Musikmesse instrument trade show in Frankfurt, where they saw a live band perform using TubeSync technology for the first time.

He said: “It was being used by a band playing Pinball Wizard by The Who. We’re expecting to see the technology on stage properly some time this year.

“The lead time on the product is about eight weeks so it could well be appearing in the summer.”

British amp manufacturer Hiwatt, whose users include Arctic Monkeys, The Killers and The Kooks, has incorporated TubeSync into its amps and Andy says that others, such as fellow Brits Orange, are keen.

The company is talking to manufacturers about fitting it in amps this year and down the line it may create variants of the product that could be fitted by amp technicians or even end users.

Hiwatt launch TubeSync at the Frankfurt Musikmesse 2010

Thursday, April 1st, 2010

Famed for their legendary reliability and tone, Hiwatt have gone one step further in the reliability stakes by employing TubeSync® technology in their already bulletproof amplifiers.

Over the last year, Hiwatt and Durham-based KBO Dynamics have developed their own version of a pioneering technology called TubeSync®, which Hiwatt will launch at Frankfurt Musikmesse 2010 in March. The technology has been developed in order to overcome problems associated with conventional tube amplification such as biasing, tube longevity and overall reliability. What the collaboration has achieved is to improve amplifier design without changing the fundamental amplification process yet retaining the classic Hiwatt tone and sound.

Hiwatt Launch TubeSync

Although not an integral part of the amplification process, Tubesync® is connected to the heart of the amp’s circuitry, constantly testing and monitoring; it’s like having an amp technician working full time inside the box every time the amp is powered up. This technology eliminates the need for tube bias current matching, increases tube life by micro-adjusting the bias on each tube, predicts tube failure and can, in the event of a catastrophic tube failure, even run the amp at half power. The result is the eradication of many of the problems hampering conventional tube amplifiers and peace of mind for the musician wise enough to have taken this route.

KBO Dynamics Chief Exec Andy Fallon: “It has been a pleasure working with Hiwatt who have been extremely receptive to change and have embraced the new technology. They have seen the benefits it can bring to them and of course, their customers, and we are looking forward to further exciting collaborations. This technology genuinely has raised the bar concerning reliability and classic tube amps, and what’s more. It’s been developed exclusively in the UK.”

JJ Electronic Tubes / Valves

Monday, March 29th, 2010

All materials used in the JJ tube  manufacturing process must comply with the most stringent quality requirements. In tube manufacturing, the fundamental requisite for the best production results is to maintain as high mechanical precision for assembly as possible. JJ Electronic uses assembly precision of no more than ± 0.02 mm.

Before tubes are assembled, they are thoroughly cleaned using such methods as the ultrasonic bath, chemical cleaning or annealing in an inert gas atmosphere (hydrogen, nitrogen).

A thorough inspection is performed on every component of the tube internal system before assembly. Assembled systems are then sent to sealing in a glass envelope. During the sealing procedure, the temperature of the glass pass-through joints must be controlled and joints are gradually tempered to relieve the inherent thermal stress.

Next, the assembled glass envelopes are evacuated by mechanical and diffusion vacuum pumps. During this process, the cathode emission coating is activated. All internal parts are heated by a high frequency heater and any spurious dust particles are evacuated. Finally, the getter rings are activated, while they absorb any residual gas inside the glass envelope of the tube.

Every tube is then electrically tested for all parameters which are the key to a flawless operation and a great sound. Specifically, these parameters include: leakage characteristics, internal vacuum level, cathode emission capability, filament voltage and current, anode current saturation level, microphony and others.

Every month, random samples are taken from the production line in order to perform a life time test of 5000 hours under nominal conditions or 1000 hours at maximum specified ratings.
