Audio Note Neiro Power Amplifiers (pair)

The Neiro mono block power amplifiers use a pair of 2A3 output valves in a parallel single ended design, fed from a 6SN7 triode. Using a pair of 2A3 triodes produces approximately double the power of a single one which makes this small valve accessible in a much wider range of systems than would otherwise be the case. The classic 6SN7 dual triode drives the output valves via copper foil in oil capacitors. Elsewhere the component quality is very good, as you'd expect, with output transformers that combine copper primary windings with silver secondaries on UNHiB double C cores, along with Tantalum resistors and silver internal wiring.
