Royal Directly Heated Triode Preamplifier
The Royal has 3 line level inputs that are selectable into a custom input transformer. This transformer isolates the input from either the Penny and Giles volume control, or a remote controlled volume control (your choice). The volume control feeds the 71A tube used as a gain and output tube. Therefore only one device is used per channel. The input transformer assures the Royal to be true in phase. The 71A known as a Directly Heated Output tube is hefty enough to drive any type of amplifier.
MSRP $7500, with silver input transformer = price on request.
