I have a j-box that looks to be from a Model I system but I'm not too sure. Does anyone have a pic of one please?

Not the greatest pix, but give it a shot... I'm sure I have better ones somewhere...

Good Luck,

Erwin

Thank you Jerry. I was just waiting for someone like you to pop in and save the day :) Thank you kindly. I just got me an archer topstage and just wondering what to do with this dying breed. May I ask, are these still used today in any situations?

Charles;

Sadly these are not worth much any more, in my opinion, unless you have a 3A sled to use it on.

This one looks to be in great shape, virtually new.

The problem is you've got to figure out how all those connectors are wired and then mate it to the bottom connector.

Those top connectors are not used anymore for the power, FF and other options.

Get what you can for it.

This seems to be a 'whatever-you-can-get' item.

If you need a j-box you can make one from the "right connectors" and a fuse and some parts from Radio Shack.

Maybe hold onto it until you find someone who has a 3A and needs one then see what you can get.

Good luck.

JA

This box might still be of good value.

If you are good in electronics or know someone who is. these boxes can be very handy.
I used the smaller part, with the electronic bubble level, to make a level indicater with LEDS. This is very easy, with the right chip, LM 3914
(http://www.national..../LM/LM3914.html) you can make a nice little box, which is sensitive to the angle and which you can mount on your rig.
I build this when I sacrificed my IIIa system and still use this on my LCD, it has 4 HiBright LEDs on either side of a big Green LED and it is very helpful to see from the corner of your eye.

The bubble level is sensitive to speed changes so not always reliable but until now, I have been very happy with it.

Rob

Hey Rob, now that is a smart idea. SAlthough I'm not an electronic genius I might know someone who is. Gotta a pic of this item on your monitor? I would like to see it. Thanks.

Charles and all, I uploaded a movie to You tube, so you can see how it works and where I placed the parts.

Basically, the level is mounted to a place closer to the post, to avoid speed/acceleration-interference. my level is mounted on a plate under the monitor attachment (Yes, I have a Franken-rig :rolleyes: ) and a coiled cable goes to the little box with the LED's and the display-IC board and this is attached with Velcro on my monitor, or anywhere i want it. Can be handy for some extreme low or high shots to re-position the LED-box.

Best,

Rob
