DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier6524 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 amplifier5197 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 Amplifiers5362 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.
