DIY-LM3875-Gainclone~0.jpgDIY LM3875 Gainclone - rear view4220 viewsA gainclone chip amp with an external power supply. The design is based on my Roasting Pan LM3875 Gainclone Chip Amplifier. All wiring is point-to-point.
Fostex-FE127E-DIY-Bass-Reflex-Speaker-2.jpgFostex FE127E Vented Bookshelf Speaker5256 viewsPhotographs of the finished bookshelf speakers on a speaker stand. The enclosure is based on the Fostex FE127E Bass Reflex Bookshelf Speaker design by Rabbitz.
The enclosure is made from 15 mm MDF and is well braced. The woodworking and finishing of the speaker cabinets was done by a friend.

This build follows the KT77 Push-Pull Tube Amp instructions by Bruce but as mono-blocks.
RH84_-_SE_EL84_Tube_Amp.jpgRH84 - SE EL84 Tube Amplifier2478 viewsThe first tube amp I built and I love the sound... pentode power with triode sound! The amplifier topology is the RH84 from designer Alex Kitic. I am using JJ EL84 and Sylvania 12AT7 tubes. The most important aspect of this ingenious design is the plate to plate partial feedback without global feedback, 2nd harmonic distortion is slightly increased giving the impression of listening to a SET amp. Damping factor and bandwidth are also improved. The OPT are from a salvaged an RCA console - a gift from Dave of Planet10 (thanks).
What a great amp !

DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier2912 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 amplifier2221 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 Amplifiers2377 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 Amplifier1994 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.
