4-channel-400W-amplifier.jpg 4 channel, 400 W amplifier310 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 Amplifiers282 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 Amplifier279 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.

Decware-inspired-EL84-amp.jpg
Decware-inspired-EL84-amp.jpgDecware inspired EL84 amp with attenuation300 viewsThis is a Decware inspired EL84 power amp with attenuation. My twist was to make a it a EL84 SE UL (not triode). Also I upgraded the PS a little. One PS tweak was to use a Russian PIO 4uf cap as the first cap in the PS. Also the larger electros are all snubbed.

The inter-stage caps are Audio Note Tin foil, mylar and oil. The amp I called "Tamarisk" - just like how it sounds. The finished amp looks good and not too heavy. Sound is a big step up from my already great sounding 6V6 - Ozzie tube SE UL amp. On live classical every part of the music has a layer. There every instrument is heard in its own layer and decay, reveb etc also have their own layers.
