It was an amp I built with some reference to Decware ideas. I have great respect for the Decware amps and design.

Partially inspired by Decware design and Bruce Heron of oddwatt loving the EL84 I built this amp. My build was a SE UL with Audio Note Tin foil caps, National NOS EL84s, Alps Blue Velvet pot and Ozzie Spotted Gum base. Sophia mesh plate rectifier tube.

Hammond iron and Edcor OPTs with WBT silver solder used throughout. When it came up for re-sale I nearly put in an offer to buy it back. It was really that good.

Decware strap the EL84s as triodes and tie the screen grid to the plate. In my build the OPTs have a feedback tap on the primary winding of the tranni. That tap sends part of the signal back to the screen grid to act as local NFB.

This allows the amp to generate a little more power, extends the frequency range and to me sounds better all over with more solid bass.
