EL84-SE-Tube-Amplifier.jpgEL84 SE Tube Amplifier Project5360 viewsThis is my Single Ended EL84 / 6BQ5 Tube Amplifier project. See my webpage for the schematic. Half of a double triode tube (ECC88 / 6DJ8 or ECC82) amplify the input signal for each the EL84 / 6BQ5 tubes. The speakers in the background are also DIY and use a single Panasonic fullrange driver.

TeaBoxInsideSmall.jpgTwinings Tea Box 12AX7 Tube Preamp with External 5Y3 Power Supply3249 viewsIn this build I used the Jensen copper, paper and oil caps for the input, output and inter-stage coupling and Solen Teflon for the feedback capacitor. The preamp is a two stage triode (12AX7s AWA-Australian) with global feedback and is the original Silicon Chip design with some modifications. They are bigger caps all round and no printed cct. brd. Construction of brds. was component-2-component wiring which means there is NO additional wire used on the brd. construction. At the brd. level this is better than point-2-point wiring. This cuts down on soldered connections/junctions and cct. length. All 99.999% pure silver wire with heat shrink insulation is used in the signal path to connect brds. to RCAs and Alps blue velvet pot etc. Medium gauge OFC hook-up wire brings power to the brds. Heavy bituminised Al foil lines the light timber case to provide a ground plain and RFI/EMI shielding. The remote PS employs a 5Y3 rec. tube (Australian made in this case) Hammond 370X power tranni 193B 12H choke.

S5-K16LS-Tube-Amp-Kit-Mahogany.jpgK-16LS Tube Amp Kit (16W)6170 viewsThe S-5 Electronics K-16LS tube amplifier kit built into a Mahogany case. The tube amp kit was built with all the mods outlined in the forums here at diyAudioProjects.com. The circuit board was built with components (except the tube sockets) on the bottom side so just the tubes would be exposed. The front driver tubes is lit red with LEDs.

DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier7076 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 amplifier6065 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 Amplifiers6305 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 Amplifier5254 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.
