Coda 60.0 Mono Amplifier - Manual (Page 7)

I. Design Philosophy and Approach (continued)
To maintain “Precision Bias” requires an advanced bias circuit that must have a very
high degree of stability under a wide range of temperatures and load conditions.
networks are of such high impedance and poor thermal regulation
that at the extremes of operation, bias currents are controlled. Advanced
tracking techniques used in the 60.0 result in absolute control of bias currents under all
conditions.
The main power supply of the consists of two 2000VA toroidal power
transformers (or one 3000VA transformer in the EU) with independent to
isolate the channels from one another. 184,000 microfarads of total capacitance
provide
These attributes result in a of such extreme linearity and bandwidth that no
overall feedback correction is required or used. One advantage of this is a high
degree of immunity from interactions with loads or cables and a superior transient
response. An extremely low nonreactive output impedance is maintained well beyond
20,000 hz. The resulting uniform damping factor is not commonly found in other
designs.
The chassis of the 60.0 is constructed of machined aluminum milled to very close
tolerances yielding the seamless appearance characteristic of previous products
from Coda. As with all high-power heat dissipation is important. The 60.0
uses six massive aluminum heat sinks without fans for noiseless, and clean
thermal relief. The thermal of the 60.0 heat sinks is one of the lowest and
most in the audio industry.
