DIY-50EH5-25EH5-Tube-Amp.jpgDIY 50EH5 / 25EH5 Tube Amplifier3507 viewsThis tube amplifier project uses the parts from a junked Fleetwood console stereo. It uses a 6AX4 full wave bridge rectifier two 5A 400V fast recovery diodes. The preamp tube is a 12AX7 and the power tubes are 50EH5. I followed the basic ideas from Gio's DIY 50EH5 Tube Amplifier Project. This is my super sized version of the amp with all DC regulated filament supplies and even does a lower frequency response than usual because of larger output transformers (underneath the chassis).
OddWatt-KT77-Push-Pull-Tube-Amp-Kit.jpgOddWatt / OddBlocks KT77 Push-Pull Tube Amp Kit2799 viewsA photograph of a finished OddWatt / OddBlock KT77 Push-Pull Tube Amplifier Kit. The KT77 tube amp kit is available from OddWattAudio.com. The kit comes with a NOS JAN Philips Branded 5751 (US made) and new production JJ branded KT77 tubes (Russian made).
Complete instructions to build a similar DIY version of the amp are available on the Oddwatt 225 - 6SL7 SRPP / KT77 SIPP (Push-Pull) Tube Amplifier project page.
RFTUBES.jpgRF tubes in audio use2520 viewsThe use of RF tubes in audio amplifiers may be a good option and saves some money. Here you have the descriptions of some experiments done in this field. For details see http://diy-rbt5.tripod.com/
OddWatt-225-6SL7-KT77-PP-Tube-Amp.jpgOddWatt 225 (driver 6SL7, output KT77 push-pull)2634 viewsThis is my version of the OddWatt 225 (push-pull) tube amplifier project that I built following the instruction on this website. The output power is 15W in pure class-A operation. The amplifier can be used with KT77 and 6L6GC output tubes.
I'm using the push-pull KT77 tube amplifier with my DIY Turntable (record player) which is a featured project on the website.

DIY-6AS7-Tube-Headphone-Amplifier.jpgDIY 6AS7 Tube Headphone Amplifier5793 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 amplifier4478 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 Amplifiers4596 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 Amplifier3747 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.
