Lot of various transformers and inductor based band-pass filters.
Top row:
6 x Collins/UTC inductor based band-pass filter
1 x Transformer
Bottom row:
8 x Oscillator transformers for tone generators (for organs)
1 x Transformer
Apart from the small open frame transformer on the bottom row, all of the inductor based filters and oscillator transformers are potted. Although these are all band limited, you can chisel away the potting compound and disconnect the internal capacitors. This will essentially convert them back into straight transformers which may (or may not) perform sufficiently at audio frequencies. But then there are 16 of them and they come to £1.25 each. So, the whole lot is for experiment.
GBP 20.00 plus shipping and paypal.
