  • Strange additon to speaker out on 147 leslie

    Picked up this leslie in pieces. Many weird things about it including what looks like a choke of some kind inserted into the speaker out line heading up to the cross over? Any ideas on why this might be here. Does not seem to add any resistance to the circuit but maybe some inductance?

    that looks like a filter. Perhaps for additional noise reduction? Looks like an extension of the filtering used in the cross over for the horn ?

      I've mostly given up trying to figure out the bizarre things I run into in vintage musical gear. People do all sorts of experiments and leave them in place even when they don't work.

      My advice is just to put things back to the way they're supposed to be. Don't get drawn into the madness.

        I suppose I could just jumper it and see if there is any difference.

          It's not meant to be there, so I'd just bin it.
          It's not what you play. It's not how you play. It's the fact that you're playing that counts.

            This is exactly how how I almost fell into hoarding, not quite there, but close. Why can't I throw away old y connectors, many cords with phono plug ends, screws or bolts or washers or nuts that I very strongly suspect came from somewhere inside the B3 or A100 or Leslies but can't remember where the heck they are from? So I "bin" them. I needed one pedal contact "tang" that was broken when I bought my A100. I found 25 on eBay for $25. So I have 24 left. I would never need more than 2 or 3 more. So they are "binned." The list goes on and on.

            Throw it out! Only then will you find out that the copper is worth 40 dollars and someone is willing to pay $300 for that specific part. And Andy would once again be right.

            And this neurosis only gets worse as you age...

            Sheesh...

                Looks like someone's attempt to create an impedance mismatch 'to improve the sound'...
