Re: Selga 405 audio problem.
Begs the question of how the transformer broke free from the PCB But the rest of the radio is pristine

Re: Selga 405 audio problem.
I'm quite impressed by the sensitivity of this radio, It might have some design peculiarities and it isn't the best build quality, But it works well.
Thanks to peter sol for donating the output transformer, I came across an old post which states the output transformer spec for the 404 model, I'm presuming the 405 uses the same transformers. Primary: 2 x 225 turns, 0.15mm wire, 7 Ohm Secondary: 60 turns, 0.35mm wire, 0.6 Ohm Jay
