Here part of the schematic for reception and amplifier
The amplifier is a little different from the V6
I changed the C38 to 220µ for POP, but reduce, not eliminate.
For amplification, it lacks strong enough power in the speaker
I wonder if it was a good idea to
multiply by 2 the secondary t16 respecting the phases. Make a kind of Fivecoils respecting the phases. After that remains to add an amp module, or change some values on chain amplifier to get more power?
