2SK1058 Mosfet Amplifier - Inside1903 viewsSergiy Makharchuk build of Mark's simple DIY Class A 2SK1058 Mosfet Amp Project. Here Sergiy has used light bulbs in place of the load resistor. The enclosure is recycled from an old piece of physiotherapy equipment.

50L6GT Tube Amplifier481 viewsThis little guy is something I came up with when a friend asked me if there was an inexpensive, but decent vacuum tube amplifier he could build. Well, it is low cost and sounds acceptable, but it is dangerous as one side of the AC line is connected to the chassis. Yes, I used a polarized plug, but it also depends on the receptacle being wired correctly... so I recommended that he should build it with an isolation transformer.

It uses two 50L6GT output tubes driven with a 12AX7A. The heaters are series strung with a 68 ohm resistor to take up the remaining 8 volts. The powersupply uses a 1N4005 half-wave rectifier, so it was a bit difficult to filter out the 60 Hz buzz.

For something cheap, it doesn't sound half bad. Though, it doesn't hold a candle to my 6T9 Push-Pull Tube Amplifier!

DIY-Speakers-and-Subwoofer.jpg
DIY Speakers and DIY Subwoofer 116 viewsI just finished building some budget speakers and subwoofer. Very basic design but that is the look I was after. It is my first project so I kept the components cheap. It sounds quite good considering the cost. Certainly a lot better sound than the speakers I was considering which cost 5 times the amount. Also I had fun and learned a lot along the way.

To get a perfect gloss finish and without the need to bog and sand screw holes, I first screwed the 19mm MDF together and then laminated (glued) 3mm MDF over the top. Next I trimmed the edges of the 3mm MDF with a router fitted with a laminex trimmer. After a light sand the boxes were ready to finish with no chance of seeing any screw holes.

I also made a cabinet to match and used some perspex for the centre panel and sprayed it the same colour as the subwoofer.

I hope this has inspired any budding diy speaker newbies. Im hooked now, im already planning my next project with better components.
