wrote: What's the quickest and simplest way of running an 8 ohm earpiece to a 32 ohm earpiece output socket without suffering too much power loss? ====== Any small transformer with a winding ratio 2 : 1 . Check with low voltage -50 Hz , 1 V in ......0.5 V out. Ratio is not all that critical . You can also use a tranformer's single winding with a centre tap . Thanks, Frank. Turns out on further investigation the circuit specifies * two* 32 ohm insets in series for 64 ohms altogether. I've still only got an 8 ohm earpiece, though. So that's an 8:1 transformation which adds up to.... a tap a quarter way along one winding? Or is it three-quarters. Or of course a full, 4:1 transformer, I suppose. I always get confused with transformations, for some reason. :-/ -- "What is now proved was once only imagin'd." - William Blake, 1793. |
