Based on my recent (positive) experience with the construction of an OTL (mono) guitar amplifier I have decided to try the construction of a stereo OTL too.
After a careful evaluation of the published schemes available over Internet (and in the links of this valuable forum)I have synthesized the attached one, a sort of pout-pourri of ideas of others that suits fine to me.
My design driver has been a personal desire for the simplest(and less harmful) power supply (+140V/-140V and negative bias only)and for low parts count.
At the same time I have also tried to minimize the number of coupling capacitors (2 + 2 non electrolytic caps only).
I will greatly appreciate any hints, comments and suggestions on the attached scheme (before construction).
