Matthews Posted December 28, 2015 Share Posted December 28, 2015 (edited) These crossovers are labeled "type A". However they look much different than the current Crites type A offerings. What do I have here? Also, there is one loose wire (red) at the top middle of photo. Both x-overs have this loose wire with no apparent place for it to connect? Just a little odd and made me curious... Thanks edit: whoops, forgot the photo Edited December 28, 2015 by Matthews Quote Link to comment Share on other sites More sharing options...
babadono Posted December 28, 2015 Share Posted December 28, 2015 I assume (here I go again making an azz of u and me) its Bob Crites' implementation of a Klipsch Type A network. See the crossover thread pinned at the top of this forum section. Hope this helps. 1 Quote Link to comment Share on other sites More sharing options...
Jim Posted December 28, 2015 Share Posted December 28, 2015 Give Bob a call/email tomorrow. Send the picture to him through email and see what he says. 1 Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted December 28, 2015 Share Posted December 28, 2015 (edited) I'm sure it is one of his… Older, different types of can caps. There is another part of a thread somewhere in the Ethereal forum that has something else about these particular crossovers and these capacitors.

wvu80 Posted December 28, 2015 Share Posted December 28, 2015 (edited) Also, there is one loose wire (red) at the top middle of photo. Both x-overs have this loose wire with no apparent place for it to connect? I don't know the answer, but that doesn't stop me from guessing! I thought on some networks changing the position of the tap on the capacitor changes the XO point or maybe the attenuation. Could this be pre-wired so the customer can simply plug and play to get a different value? Edited December 28, 2015 by wvu80 1 Quote Link to comment Share on other sites More sharing options...
Mighty Favog Posted December 28, 2015 Share Posted December 28, 2015 (edited) I'm gonna take a stab and say that extra wire is to change the attenuation to the positive lead to the squawker (nearby positive lead with the same male to female connection).

OO1 Posted December 28, 2015 Share Posted December 28, 2015 these are A networks from Bob Crites - http://www.critesspeakers.com/ - BOB stopped using GE cans a few years ago -so these are either 10 or 5 years old - now if you have a serial number in the back of the board - BOB can give you the exact details as to the specs - 1 Quote Link to comment Share on other sites More sharing options...

Frzninvt Posted December 28, 2015 Share Posted December 28, 2015 Those look like Bob's convertible networks, by swapping leads you can convert it to an "AA" network. It is designed so you can switch it between and "A" and AA" on a single network board. I had a pair of them at one time. 1 Quote Link to comment Share on other sites More sharing options...

Matthews Posted December 29, 2015 Author Share Posted December 29, 2015 Did you get those at least with the Scalas? The Scala's came with the stock AA crossovers. I bought these separately. Save me from having to re-cap the originals. Quote Link to comment Share on other sites More sharing options...
Matthews Posted December 29, 2015 Author Share Posted December 29, 2015 So I am a little curious? If these are convertible, do I just switch the lead (red)? Will there be a noticeable sonic difference between the two? Is it even suggestible to fiddle with it? Still a few weeks out yet, just curious...

I had a pair of them at one time. that answer is plausible but the AA network adds Zener diodes for tweeter protection to an A network -and there are none on that board -now that red lead looks like an Lpad to select an attenuation point - 1 Quote Link to comment Share on other sites More sharing options...

Still a few weeks out yet, just curious... yeah - the red lead on the 3636 autotransformer can attenuate any value from -1 to -12 db , so from the picture of your board , I am guessing a -3db or plus 3db sonic difference depending on the lead you chose --the lead is connected to the no 6 on the terminals post - and that is the squawker only - Edited December 29, 2015 by Randyh Quote Link to comment Share on other sites More sharing options...

Matthews Posted December 29, 2015 Author Share Posted December 29, 2015 So are these crossovers, perhaps, somewhat a rare find? Quote Link to comment Share on other sites More sharing options...

Matthews Posted December 29, 2015 Author Share Posted December 29, 2015 these networks must have had a couple of midrange drivers that he could swap in like a K55V or a K55M - since some drivers are hotter than others My drivers are the K-55-V. Will it be safe to switch between the two leads? Decide which one sounds better to my ears? -now if you want to improve on that network - you can add Zener diodes for the tweeter protection to avoid blowing these , on the board making them into an AA network -or an A network - if unused - I am in so far over budget on this project - perhaps an addition for later down the road...
