EL84 / 6BQ5 Push Pull Tube Amplifier822 viewsThe "OddWatt", a EL84 / 6BQ5 Push Pull (PP) Tube Amp project. SRPP input stage and ultra linear output stage with LM317 Regulators CCS. Tube heaters are 12VDC.

Phono Preamp Ki.920 viewsThe cct. brd was assemble and the ABS plastic case drilled ready for assemble. ABS is a very hard plastic to drill. Before assembly the lid, base and sides were lined with heavy tar and foil stick-on shielding. This helps with case dampening also. All gold RCA connections were kept to the rear (see other photos). The chips are the LM833s but the Burr-Brown OPA2134 high performance chip can be directly substituted. The on-board +/- 12V regulated PS is shielded from the rest of the sensitive cct. Additional snubbing was added to the line caps to remove PS noise and chip RF decoupling. Though three different compensation can be selected from the cct. brd by moving two jumpers the lid must be removed to do this. A double pole rotating three position switch could be added to provide this facility externally. The cct. includes a gain control which is accessed from the front and allows easy and silent level adjustment. The sound is natural with no hiss or hum. Easy to build.

Tang Band D4-1 DIY Back Horn Speaker Kit10 viewsThe fun and simple Tang Band D4-1 DIY Back Horn Speaker Kit. This little speaker kit comes complete with all the parts and tools required (minus a soldering iron). There is no cutting or finishing required (no saw dust or fumes!). The kit is very simple to build as it goes together just like ready-to-assemble furniture.

Don's 6C33C tube amp from Down Under with locally wound OPTs53 viewsThis beautiful amp is not one of mine but belongs to a regular customer of the electronics store I work at. The power tubes are the same used in Mig fighter jets as regulator tubes. Don has dropped one on a wooden floor, it bounced and he caught it. Tough tubes. The timber base is made by Don and the top plate is 4mm thick ABS plastic. The power trannies and chokes are well separated from the music making bits. He employed locally made horizontal power tranni, chokes and OPTs. The amp is musical and neutral sounding low bass is a little spongy and undefined when added to my all valve system. It produces 15W, not bad from a SET. The front tube is a Sovtek 6SJ7 and the amp is two stage and weighs 40lb! Mark – contributorMar 05, 2010
