c70 is a scaled down version
of the c200. This does not imply an inferior performance,
but rather a slightly simpler circuit due to the omission
of the output protection network. Power output is
less as the ever popular 2N3055 and MJ2955 are used.
Properly constructed, it is surprising how good an
amplifier can sound even with these "ancient"
supply requirements for 1 channel of c70 is a 25-0-25Vac,
100VA transformer for a supply rail of +-33Vdc. Filter
capacitors are 2x10,000uF/50V. Output unclipped power
is 45 Watts/RMS into 8 ohms and 70 Watts/RMS into
further information and power testing, kindly refer
to the c200.
