Marantz Model 1060
¥ 54,900 (around 1972)
Pre-main amplifier designed by Marantz U.S.A. and checked up according to the Marantz U.S.A. standard.
The equalizer is a 3-stage direct connection NF type using 6 transistors, and basically has almost the same circuit configuration as #7T.
The tone control section allows control of the mid-range range. The control width of the low and high ranges is approximately twice that of the mid-range range in consideration of the effect of hearing.
The main section uses an orthodox quasi complimentary service circuit.
The protection circuit is an ASO detection type, and there is no need to worry about skipping the transistor even if the output is short-circuited due to misconnection, etc.
According to the Marantz standard, it is designed so that no oscillation occurs even when a 10 μ F capacitor is loaded.
