I've been collecting parts for some amps using 45 triodes but yesterday heard an A2 amp using high mu transmitting triodes.
I was blown away by the capability of what was a circa 10W single ended amp. As well as having a great midrange and top, the bass extension and clarity was exceptional.
I am now tempted to try this approach but I fear it will be outside my comfort zone.
Has anyone here heard or have experience of A2 operation for amps?
