Velleman-DIY-Audio-Kits.jpgTwo inexpensive Velleman kits5780 viewsA preamp & amplifier kit that I'm going to combine to make a small integrated amp.
The preamp has volume and separate bass & treble controls.
The amplifier uses a TDA1521 IC.
Fostex-FE127E-Sealed-Bipole-Loudspeaker.jpgFostex FE127E Sealed Bipole Loudspeaker7512 viewsMy version of the DIY Fostex FE127E Sealed Bipole Speaker build.
Push-Pull__Amplifier_6L6_Tube_Glow.jpgTube Glow - Push-Pull 6L6 Tube Amplifier2959 viewsThe glowing tubes of my 6L6 amplifier. The large tubes are the 6L6 output tubes and the smaller tubes are the 12AX7 driver tubes. The bright tube in the middle is an EM80. See the other photos of my 6L6 amp.

Gobo-LM1875-Stereo-Amplifier-Kit.jpgGobo LM1875 Stereo Amplifier Kit3214 viewsThe Gobo Stereo Amplifier kit is a class-AB chip amp kit based around the LM1875 IC. This is a complete amp kit that includes all the necessary parts and enclosure to build a stereo amplifier. The LM1875 amp kit comes with audio-grade capacitors and toroidal transformer. The Gobo amplifier kit is easy to build, looks and sounds great. The amplifier kit is well suited to first time amp builders.
For full details, see our review of the Gobo LM1875 Stereo Amplifier Kit

DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier6513 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 amplifier5188 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 Amplifiers5354 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 Amplifier4390 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.
