The woodworking and painting of the cabinets were completed by a friend.
2SK1058-SE-Mosfet-Amp.jpg
2SK1058-SE-Mosfet-Amp.jpg2SK1058 Single-Ended (SE) Amplifier6321 viewsThis Class-A power amplifier with zero negative feedback and 5W output audio power was built based on the schematic of the DIY Class-A 2SK1058 MOSFET Amplifier project by Mark Houston.

The amplifier uses a custom handmade choke coil.
The power supply uses 4 x 15000 µF Towa capacitors designed for Adcom.
Two large heatsinks and one 88mm fan provide enough cooling to keep the temperature below 60°C.
The amplifier is used with custom made sensitive acoustics.
The sound is very precise and detailed. It has deep sound staging and amazing microdynamics.

PeerlessSeas2way~0.jpgPeerless and Seas 2-way Towers in Zebrawood5342 viewsThe fun part about building these speakers was the crossover design with a Zobel and Baffle Step Compensation (BSC). I wanted to try a larger driver than a 6.5 inches. I am really pleased with the sound and image. Unbelievable sound for the cost. The crossover uses open air inductors and Solen capacitors. The Veneer is Zebrawood adhesive backed. I was able to match the grain on both sides and the fronts. One coat stain and finish followed by paste wax. The speakers are drying in the garage awaiting the living room. Next is a pair of open baffle 3 way with active cross using DIY chip amps.

DIY-6AS7-Tube-Headphone-Amplifier.jpg
DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier2983 viewsMy name is Laurie. I have been building and DIYing for 45 years now and happily will never stop. This tube headphone amp is from a thread in the Form.

The power connecting cable comes from a European Travel Iron I bought for $1.00 at junk shop. (220v/6A) They will be shortened when I find a perch for the amp and me. The sound is better than my ears have ever heard so I will be keeping this one for my retirement entertainment should such a time ever come. Wink It has worked from day one and continues to please me every time it is turned on. The tubes are JJ ECC88 / 6AS7 with a 5V4 rectifier tube. To spite it's small size the parts are quite easily accessed. I over built most components so it will outlast me I fear. The only change I anticipate may be the 6AS7 to a bottle neck glass to match the rectifier tube. I do have and use a 6080 tube, but i can tell no difference in sound. It will take more then a few hours of listening to get my ears better tuned.

4-channel-400W-amplifier.jpg 4 channel, 400 W amplifier2278 viewsThis 4-channel 400 W amplifier uses Hypex UcD400HG modules together with the corresponding power supply.
The whole is mounted inside a Galaxy 330 x 230 x 80 case.
For building instructions, have a look at this project's wiki.
Two such amplifiers has been working for over 2 years in my lounge, driving Linn Komponent 110 loudspeakers which each have 4 speaker inputs.

E88CC-SV83-SET-Amplifiers.jpgDual SV83 SET Amplifiers2449 viewsA mirrored pair of SET amplifiers, presently being used in bridged mode. All P2P construction using silver solder. I included a "Hazen grid" capacitor and input tube bias change switch. The single mA meter displays individual output tube bias current with a Left/Right switch. Edcor XPRW178 power transformer and GXSE10-6-8K output transformers. Upgraded caps to Jantzen Audio 1200V Z-Superior. Upgraded resistors to PRP PR9372 Audio for metal film and TAKMAN REX for carbon film. ALPS Blue 100K attenuator. The power supply uses a RCA 5U4GB rectifier and Hammond 156R choke. Matched pairs of Svetlana SV83 for power and JJ E88CC for the input tube.

6V6-Push-Pull-Amplifier.jpgPush-Pull (PP) 6V6GT Tube Amplifier2055 viewsThis 6V6 amp was built following the DIY Push-Pull (PP) 6V6 / 6V6GT Tube Amplifier Schematic. Power Supply transformer and Output transformers are handmade in Argentina by NavasBaccino. I'd like to thank Brad S. for the help. The sound is amazing and clear, free of distortion.
