00005.jpg25EH5 / 50EH5 Tube Amplifier2752 viewsAnother view of the amplifier from the top. As you can see, I was using headphones as I took the effort of adding a jack with impedance matching resistors so I could listen to my music in peace. The funny thing is that I can apply just about any load to the amplifier without any audible change other than volume.

DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier3002 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 amplifier2293 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 Amplifiers2472 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 Amplifier2072 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.
