Decware inspired EL84 power with attenuator

This 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. If I had have paid $5K for this amp it sounds like what I would expect for that money.

  • I would love to build an amp like this - I have already built an S5 from the States which is a knockout - have you any plans or links for this amp. Cheers Walter Adelaide
