Edifier HCS5640: Hitting The Right Notes

Intech@thestar.com.my

WE LIKE listening to our media files loud and clear with surround sound oomph, so we were quite pleased to get Edifier’s HCS5640 5.1 multimedia speakers for review.

The HCS5640 is a relatively compact system in design that makes it a great fit whether you want to hook it up to your PC or home theatre system.

The entire system consists of four satellite speakers, a centre speaker and the subwoofer.

Its small satellite speakers don’t take up much room at all, which makes it well suited for a living room or media centre setting. Probably the biggest component in the system is the massive subwoofer, which needs to be set on the ground.

A single amplifier acts as the main central hub of the system, providing both power and sound output to the five satellite speakers and subwoofer.

A large volume dial sits on the front panel of the amplifier accompanied by a couple of smaller buttons around it that control the speaker’s functions and input source.

How can I build a tube guitar amplifier?

I am an experienced electronics technician looking to build an tube guitar amplifier. I have done some research but all I found were books writen in the 50s. I am interested in theory as well as materials. I am a little confused about tubes. There are so many different kinds. IE: pentodes, triodes, ballasts, rectifiers, etc... Also there are various mounts, covers and things. A big part of the reason I studied electronics was an interest in guitar amps and effects.


Hi,
I'm trying to figure that out myself , planning to build one this summer. This site I found is really helpful, it has instructions for how to build various tube amps with different tones, I think it has some theory stuff too. Check it out

How difficult is it to 're-tube' a guitar amplifier?

I have an all tube guitar amplifier that is losing some of it's clarity. I've been told that re-tubing will clear that up. How hard is it to do this? On the surface it looks like you pull the old tubes out and stick new ones in. Is it that simple? What is 'biasing'?

Thanks!


Pull the old ones out and stick the new ones in. That's all there is to it. Tubes can deteriorate over time. There are a number of reasons for this, but the most common is the loss of the cathode oxide coating due to bombardment by the small amount of ions that the getter has failed to remove during manufacture. Not all tubes will deteriorate at the same rate. My point is that it is proably unnecessary to change all the tubes. Try and find someone who will test them for you.

If you can't find someone with a tube tester. Try changing them one at a time to see which one restores the sound. It is usually the power output ones that go first. Try looking at the tubes in the dark. If they glow blue, that suggests that there is gas inside. Even new tubes will glow blue, but a tube that has been glowing blue for a long time will probably have lost some of its output and will be starting to operate outside the desired region.

Biasing is the application of a small negative voltage to the grid to bring the tube into the linear region. In the old days, (and I am talking about a very long time ago here, when valve equipment was usually powered by batteries because very few people had mains electricity) this was done by a separate battery. Then someone realised that by simply connecting a large value resistor between grid and ground, the grid spontaneously adopted a negative voltage. Selection of the resistor value, known as the grid leak, sets the voltage. In a properly designed amplifier with in-spec tubes, the grid bias will be automatically correct.
