Hi Everyone. I just picked up a 115RH over here in Sweden. Unlike some pictures I've seen online, mine has two input jacks. It sort of looks like this (though I can't really see what's going on in this picture too well): http://www.talkbass.com/forum/f15/woohoo -got-musicman-115-rh-cabinet-today-27208 9/ Neither one is dead center, so there were clearly two to start with. Also, the previous owner removed one and installed an XLR jack in its place. Some questions: 1) Were the jacks originally both identical 1/4" jacks? 2) Why would this have two input jacks, is it so I could daisy chain another speaker in series? If so, how are they supposed to be wired? I think right now he has them in parallel (though I would need to look again to be sure). 3) Are the European models different from the US ones? Other pictures that I saw only seemed to have one jack on the back. best DT | ||

The ones that we sold had two 1/4" jacks just wired in parallel. Tip to tip and ground to ground and then on to the speakers. They WERE intended fof "daisy chaining", which is in parallel. | ||

8ohm MM cabs have two jacks wired in parallel. If you run two cabs you run one wire from the head to the first cab and second wire from first to second. If you are running one cab with a 112 or 115 dual channel combo, you can unhook the internal speaker from the amp part and into the second jack on the cabinet. The net result is 4 ohms in each case. Of course, if you run a single cab with a single channel combo, you merely hook the cab to the combo and set the control to 4 ohms. As MM always used 8 ohm speakers, a 115RH is 8 ohms in its stock form and so got two jacks. I have never heard of any MM cabinets being different for export use. Clear as mud? Cheers/hejhopp, Lars | ||

When building cabinets, I always use 2 jacks for the reason you listed Lars, but also, if one fails, the other is there. (I have had jacks unscrew themselves on the way to the gig, and fall into the cab!) | ||

Ah yes, that's a classic. Also somebody ramming a piano or PA speaker on wheels into the jack sticking out followed by the sound of 'oops'.  | ||

Hi Everyone, Thanks so much for the clarification. Does anyone have any idea where I could get an input jack cup plate for this thing? The closest thing I have found is the old round telecaster input jacks. But maybe one of you know of something that would provide a closer match? best - DT | ||

Pretty much everything here. http://www.reliablehardware.com/jackplat es.aspx | ||

Hi Mike. Thanks for the link. I'll probably just try one of these http://www.allparts.com/AP-0275-010-Tele caster-Input-Cup_p_331.html I'm sure other options would work, but only the telecaster input jack even remotely looks like the original MM one. I doubt many people have needed to replace this part, so perhaps I am alone in my quest for one  best DT | ||

DT, I used to buy Peavey carded jacks, with black plastic cups, (suitable for 3/4 depth). I just did a quick search, and didn't find anything. I'll look at my parts box when I get home, and see if I might have a part number. | ||

DT, Peavey #00053300 has the 2 piece cup, and a switchcraft jack. |
