Set Signature Amps (2) The YBA Signature Amplifier is a monoblock, compact, but
very heavy amplifier attractively finished in black anodized aluminum
with black heatsinks running the length of its sides. There is a power
switch on the front concealed by one of the handles. The rear has a
balanced and unbalanced input and the output channel has two sets of
speaker level outputs for easy bi-wiring.
The interior holds C-core
AC transformers mounted on sorbothane washers just behind the front
panel to reduce vibrations. The output devices are mounted on mica and
copper in order to reduce capacitive effects. Cooling surfaces are
overdimensioned and printed circuit boards are double the usual
The amplifier is very conservatively rated at 100Wpc at 8 ohms and 200Wpc at 4 ohms.
