Design synopsis:
The model uses two occidental pentodes EF80 to amplify signal from the left and right channel respectively and tow occidental triodes 6080 or 6AS7 with low internal resistance as cathode output of the two channels. The left channel and right channel are supported by different power supply. The capacitance and resistance use Israeli VISHAY.
