Can someone have a look at their speaker connection on 112 , is it yellow to the + or blue.
I have a second hand amp and not sure if they have wired wrong.
having tried the blue to + and the yellow I seem to get a better sound with the blue to the +..but I feel that it must be the yellow to + thanks |

On an amp with just one speaker, like the 112 it doesn't matter which way the wires are connected. Keep in mind audio is an "alternating current" signal so for 1/2 of each cycle (Hz)one side is positive and the other side is negative, and for the other 1/2 cycle it's reversed - the side that was negative is now positive and the side that was positive is negative.
If there were more than one speaker then polarity needs to be observed. Or if your were going to use two amplifiers you want them both to be in phase. |

| Thanks Jack, I was wondering why it sounded better with the wiring the other way around. |

According to a book on vintage amps, speakers wired so that a positive input signal to the amp makes the speaker move forward have more apparent low end. Apparently the old Jensen speakers used in early Fender Bassman models were marked the opposite of the modern convention, but since the amp itself inverted the signal it still ended up being a "forward playing" amp.
I'm baffled as to why it would make any difference as long as all the speakers are in phase, but that's what the author, Gerald Weber, claims in A Desktop Reference of Hip Vintage Guitar Amps.
It would be interesting if you experience confirms this. |

| But, as I mentioned one side (lead) is not always positive and the other always negative. One half of the cycle one lead is positive and the other half of the cycle the same lead is negative. Basic Electronics "101". |

Yeah, I said it was baffling. I'm naturally skeptical of such things, so this will go on my list of bizarre claims.
OTOH Gerald Weber is pretty well known for writing about guitar amps, and the OP did say that one hookup sounded better than the other. Plus, how could you not believe this man?

I found that with the yellow to + it sounded very bright to the point that I was hearing the top strings
were sound very shrill. the blue to the + the sound was more normal sounding, about what I would expect from the amp settings... |

I won't argue with what you hear. Just that electronically with a single speaker, it makes no difference at all.
My background is Electronics (including ham radio - I was ZD8JES in late 60's on Ascension Island) and Computers. And a stint as an Amplifier Tech (in Nashville). |
