SV101672.JPGBurr-Brown OpAmp Preamp II3444 viewsThis is the second of my preamps based on the high performance Burr-Brown OPA2134PA. This one has been custom built for a fellow in the US. This build has additional and switchable inputs-as you can see. The bottom and center row of inputs are selectable by the switch, the top row of connections is the output. See the DIY OP Amp Based Preamplifier page for more details.
DIY-Jordan-JX92-Tower-Loudspeakers.jpgDIY Jordan JX92 Tower Loudspeakers8905 viewsTower speaker project made around the very well regarded Jordan JX92S Full Range Speaker. The speaker box is a floor standing bass reflex enclosure. For full details about this DIY speaker project, see the DIY Jordan JX92S Bass Reflex Tower Loudspeaker page.
DIY-Vacuum-Tube-Prototype-Bread-Board.jpgDIY Vacuum Tube (Valve) Prototyping Bread Board4306 viewsA simple DIY Vacuum Tube (Valve) Prototyping Test Board used to test single stage tube circuits.
See the DIY Vacuum Tube Prototyping Board post for additional details.
12AU7-IRF510-LM317-Headphone-Amp.jpg12AU7 Tube / IRF510 MOSFET Headphone Amp4357 viewsSimple headphone amplifier with a 12AU7 (ECC82) tube voltage gain stage and a IRF510 MOSFET follower stage. A 12V SLA battery is used for the power supply. A LM317 regulator is used as a CCS to bias the MOSFET into class-A operation.

DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier4045 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.Feb 28, 2017
4-channel-400W-amplifier.jpg 4 channel, 400 W amplifier3128 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 Amplifiers3236 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 Amplifier2635 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.
