This is a quick lash up of my latest project, a copy (ish) of the Blackstar Dual-HT.
I found a schematic on the net of an early version that uses 22v AC. when I finished
it I had hum problems. The BS version has halfwave rec and this was a problem and
so I converted it to DC. The pic of the low voltage board shows two 15v regs but it#
is a bit different now because of this change.
