Default Re: AVO 163 amp board ~ transformers

Looking at the daigrams and reading the texts of the test specifications it seems like they (AVO) have designated the primary side of a transformer as the "input" side and the secondary as the "output" side.

So on the oscillator the primary side is the one connected to the output transistor and it has some 85 Ohm resistance, and on the amplifier the primary side is the one connected to the Anode circuit and it has some 0.2 Ohm resistance.
