Does Plate Dissipation Affect Valve / Tube Life In Practice ??

Thursday, November 8th, 2012

In general, the obvious connection between higher anode dissipation and shorter tube life holds good, however,  many other factors affect tube life, including accuracy of heater voltages and the efficiency of tube cooling within amplifiers.

The tube leaves the factory with a known amount of cathode coating material which is the source of all the electron emission. In use, this material is used up as it emits electrons when heated by the filament and plate current is drawn.

If plate current is drawn before the cathode is at operating temperature, the surface of the cathode can be damaged (so called ‘cathode stripping’).

This is why the Standby switch should be off when the amplifier is warming up. If, however, the tube is operated for long periods with the filament hot with little or no plate current being drawn, then an oxide-like coating can form on the cathode, effectively blocking the emission of electrons even when normal operation is required (known as ‘cathode poisoning’). TubeSync takes care of this by automatically controlling the bias at both start-up and run conditions.

Plate dissipation is generally quoted by the manufacturer as a maximum value which, if exceeded could cause damage to the tube and should not generally be used for ‘normal’ operation. The relationship between tube life and plate dissipation follows an exponential curve. Tubes operated correctly at around 30% maximum dissipation can have lives in the region of tens of thousands of hours and can last several decades of years. This figure decreases rapidly as the dissipation increases, in some cased down to hundreds or even tens of hours as they approach or exceed their maximum plate dissipation rating.

Cooling is extremely important as running tubes very hot also increases the risk of arcing and a condition known as thermal runaway, which can instantly destroy the cathode material, making the tube useless. Conventionally biased tubes are most at risk when biased towards ‘Class-A’ operation, as they experience maximum power dissipation when no audio signal is present.

What People Say About TubeSync

Friday, October 15th, 2010

Guitarist Mitch Laddie has been out touring with the product fitted to his Mesa/Boogie F-50, which he said sounds “incredible”. “I had totally fallen out of love with this particular amp before Tubesync was fitted but the difference in sound is more than substantial. The response and tone have been improved ten-fold. Very tight, very fat and all round punchier, especially in the low to mid frequencies.”

“I believe the product is very interesting and definitely nothing like anything I’ve seen or used before. The main advantages of the product are that not only does it give you a valve maintenance feature by displaying a light if a fault is found within a valve, but it manages your valves to run at an equal number of milliamps. This means that each valve is working at an equal rate which in theory gives you optimum amp performance.

“You can also connect the product to a computer and by using the TubeSync software you can dial in the parameters for each valve to your liking. This makes room for a lot of exciting experimentation,” he said.

“You can fit whichever valves you like, no matter which amp you are using with the product fitted and not only can you fit whatever valves you chose but you can mix valves and it will automatically bias them with no issues at all. This also gives room for a lot of exciting experimentation which we are going to get under way when I return from the current tour.”

Orange
Technical director for Orange Amps, Adrian Emsley, plans to launch a new 100W model involving TubeSync at the upcoming Winter NAMM show next year, but didn’t disclose any further details. He did say that he thought the product was “extremely groundbreaking” with regards how it can be incorporated into high end tube guitar, bass and hi-fi amplifiers. “It can keep an amplifier perfectly set up and keep it always sounding great on the road!” he said.

Audio Kitchen Amps, an Acton-based guitar amp manufacturer, has incorporated TubeSync into its bass amps, one of which is currently being used by Kings of Leon. Audio Kitchen’s Steve Crow commented: “It’s pretty cool, that’s for sure. For me the most revolutionary aspect is the show-must-go-on factor; normally if an output valve goes bandy during a gig it’ll take out a fuse on the amp and the player is left playing air-guitar, but TubeSync will shut down the offending valve pairs and the show goes on. Genius.”?Tired Pony, the supergroup featuring Snow Patrol frontman Gary Lightbody and REM’s Peter Buck, have already played their first live gig with the help of an Audio Kitchen Base Chopper amp fitted with TubeSync, at London’s Forum venue in Kentish Town on July 14. According to Crow the band have been “loving it” so far and there are other bands lined up to try it out.

Audio Kitchen
Crow added: “People are scared of the word ‘Bias’, but TubeSync does lots of the thinking for you so it’s possibly a less daunting proposition for the average musician or tech. Also because the valves are individually biased, you don’t necessarily need matched pairs of output valves anymore.”

Hiwatt UK amplifiers, as used by the likes of Arctic Monkeys, Coldplay, Killers and The Enemy, is another adopter of the TubeSync. The company plans to install the product on its pro series of guitar amplifiers as standard. Hiwatt’s Mark Lodge said: “Pretty much all of the bands that we deal with will start to add TubeSync to their amplifiers over the next year. We are just actually putting together the wiring practices etc, for our builders to be able to incorporate TubeSync into our UK pro series custom shop amplifiers.” Lodge said the reason they have got behind the product from the start was because it is a “fantastic” piece of kit that solves many problems associated with valve amplifiers.

Hiwatt UK
He added: “We all know that valve amplifiers sound by FAR the best, the only issue is that 99.9% of the time, the valves let the amplifier down. The deteriation can be traced back to when the military ceased to use valves; since then, the quality has gone down and down. TubeSync negates this and actually once more gives builders and performers hope and peace of mind. I think it is a huge step forward for the valve amplifier.”

Wienbrock Amplifiers
Wienbrock Amplifiers owns two 45W production amps that currently use TubeSync, one with overdrive, one without. Rob Wienbrock said: “The TubeSync takes a completely new approach that has many hidden benefits. Its main advantages are significant reduction in power consumed, huge reduction in heat emissions, greatly extended valve and component life and great reduction in maintenance costs.
BREAKING THE BACKLINE MARKET

John Henry’s will be the first backline rental company to test out the TubeSync management system. Said Fallon: “We see the backline rental market as a market for us because they do have problems with amplifiers and they have to maintain the ones they’ve got when they rent them out.
“John Henry took us round his facilities and he has hundreds of amplifiers, one shelf had about 50 marshall amps on, so we realised we needed to give him something quick to install.”
John Henry commneted: “I haven’t managed to see one in action yet but from the brief overview it was a very interesting product, there’s nothing else like it, and if it works we would certainly be interested in having a look and trying it out. Anything that can tell you when a valve is about to pop is a good thing.
“I was a little bit concerned about how you actually fit it without drilling holes and damaging the authenticity of a vintage piece of kit because as it stands it’s based at the valve market. I think they need to make one which is an external fit. So it’s in the early stages and I’d need to get my engineers to test it out, but in theory it looks good.”

John Henrys
KBO Dynamics has been working on an external fit model specifically for the backline rental market. Said Fallon: “At the moment TubeSync is a circuit card that goes in the amp, but we’ve put it into a large circuit board self contained unit. It de-skills the fitting process so the user can easily retro-fit it into an existing guitar amp in around 5-10 minutes. John Henry will be the first one to test this out.”
Added Henry: “We go through thousands of valves a year so for us it would be a great asset as we might not need to replace a set of valves but maybe just one. It has a lot of potential.”

Leaky Tubes / Valves Can Blow the HT Fuse In Guitar Amps, TubeSync Can Avoid This!

Thursday, July 1st, 2010

An interesting phenomenon that some ‘leaky’ tubes, removed from conventionally biased amps, appear to improve when run with TubeSync. The reason may be that when the tube gets hot, g1/cathode leak causes a current increase, but it is automatically biased ‘back’ to compensate, which allows the tube to cool down again and thus reduce leakage et al. After a while the leak sometimes reduces or disappears completely – we surmise that the getter  gets a chance to mop up stray gas molecules or the metallic deposit gets ‘boiled off’ the mica supports.  This type of fault in a conventional amp would normally blow the HT fuse, however TubeSync can avoid is and rectify the problem! Cool eh?

PIMP Your Guitar Amp With The TubeSync Bias Engine

Tuesday, March 16th, 2010

Pure tube magic – that warm, uncluttered sound powered by superior amp technology deserves the best. TubeSync takes care of the detail, giving unsurpassed performance from any tubes.

Plugging straight into the tube powered heart of your amp, in perfect harmony with its fine tuned circuitry, TubeSync’s Bias Engine eradicates the need for bias current matching, increases tube life and takes your tubes to their optimum temperature as soon as you power up . . .

and there’s more.

The result: a well honed tone tyrant with none of the problems hampering conventional tube amps; a streamlined orchestrator of analogue magic.

POWER UP HOT

The Bias Engine’s ‘Hot Anode’ cranks up the heat and has you running hot from the very first cord. It knows the optimum temperature for your tubes best performance and gets them there the minute you start playing.

JUST PLUG IN AND PLAY

The Bias Engine is easily incorporated into your amp’s systems at manufacture. It removes the need for bias current matching but still achieves the absolute best tone.

INCREASED EFFICIENCIES

Increased manufacturing efficiencies (due to reduced testing) are achieved by eliminating the need for bias current matching.

ROOTING OUT THE RENEGADE

Fear not the cherry red glow of a failing tube! The Bias Engine continuously monitors the performance of each tube during operation and searches for typical tube failure modes and trends. If the Bias Engine

detects a faulty tube, it can automatically ‘switch out’ the offending tube and run the amp, at half power, until the defective tube can be changed.

HARDER, BETTER, LONGER

Work your tubes at their full potential. The Bias Engine automatically micro-adjusts the bias on each tube to ensure its full potential is realised throughout its working life. The amplitude of drive signals supplied to the grids is dynamically measured and performance is optimised accordingly. Tubes work harder, better and for longer.

RAISING THE BAR

TubeSync revolutionises convention by completely replacing traditional testing methods. Every time you power up TubeSync runs an automatic ‘in circuit’ test and assures reliability.

MINIMUM POWER, MAXIMUM OUTPUT

Less power input, same big output. TubeSync reduces quiescent power consumption by an average of 20% compared to conventional amplifier biasing techniques.
