Looks like a 336 schematic:
https://community.klipsch.com/index.php?/topic/58524-ev-x336-crossover-question/
That thread also has an annotated one with all the part values.
Bob Crites sells a replacement for the 336 which is a potted crossover.
I don't know about the 325. I found the above info using Google Images.
Thanks for pumping this up! I appreciate your enthusiasm. The 336 and 325 are the same size dimensionally. The 36 is smaller. From what I see the connections are the same on the 336 and 325. But what's the difference. I'm not an electrical engineer that's for sure...I don't have much of a clue as I'm not an EV expert, but I'm kind of surprised no one has popped in here to explain it all.
Any luck finding a schematic for the X36? It looks similar to the 336 whereas the 325 looks much larger. Could be just an artifact of the pics. I can look at schematics and give some idea what the thing is doing but not based on any intimate knowledge of EV components. If this were Altec it would have already been fully detailed.
Come on EV fans, put on your thinking caps!
Thanks for posting this, will check it out!May be some clues on the crossover combinations used here:

If I recall, the 325/36 was a kit add on, with the 36 added when you purchased the T35 tweeter.
The 336 was for the wealthy, who had the money to buy all the drivers at one time. These speakers were at the dawn of wide range recording and albums, so some folks did not feel the need to buy tweeters early on.
The Georgian with the 336 sounds muted, quieter, has less crisp sound/bass than the other one. This has been a gradual issue. Am I assuming correctly that the 336 crossover is going bad?

Thanks, I really want to keep the original components, or replace them with the same. Though I may find that impossible. They are 16 ohm...I'm assuming that the 325/36 crossovers likely represented their crossover points (325Hz and 3.6Khz. These were quite common crossover points at that time). If you wanted to dispense with rebuilding/replacing the current crossovers, you could go with a very reasonably-priced OTc crossover such as the the Eminence
over BoardPXB3:3K5 3-Way Speaker Cross
I can't remember if your components are 8 or 16, but these will perform extraordinarily in 8 ohm versions with much better build quality than the original EV crossover.

Well, trying the 2 "B&P" knobs, I am finding them only allowing sound in a few positions on the dials. I had sprayed some De-Oxit in them a while ago, but was kinda hesitant to really put a lot in each housing...are the symptoms a product of this??One more thing you might try--are the "brilliance and presence" controls working properly? Have you spun them across their entire range of motion several times to ensure good contact?
I like what you did with those bass bin cabinets. It appears they have been cleaned up a bit and painted black with new risers attached. Would love to hear the back story on how you acquired these and if there were outer cabinets on them.
Lastly, I'm sure you know these are corner horns. To get the best performance they both need to be shoved into corners. You may need to build a false wall for the speaker on the right.
