Peerless 3-25 kit

[Spartoz]

Hello!
I just go those Peerless 3-25 kit from 1959, they are great and i was amazed by the design of the crossover.





They sound great but in one of the two speaker, the tweeter is not working, i tried it alone and he is working so i think the problem is comming from the crossover.

I have a spare tweeter (the same but in 8 ohm instead of 16) so is there a way to make it work? Like a separate crossover or something?

Thanks!

Woofer: 16ohm
Mid: 16 ohm
Tweeter 16 ohm but i have a 8 omh too

Goeie avond!

Can you post a schematic of the crossover or at least some pictures and the values? You can make it work by adding a 8ohm resistor between the tweeter and the crossover.

You'd guess a 50-y-o capacitor to the tweeter has conked out by now. Or maybe a dry joint or broken wire. You need a multimeter to test it all for continuity.

Just resisted calling it an AVO meter. I'm getting old too.

Oh i just saw those photos arent big sorry

So here are some more pictures

An externally hosted image should be here but it was not working when we last tested it.

So the crossover frequencies are 750 and 4000Hz
But i cant find the schematic :/
I was thinking about simply put a capacitor to the tweeter but i dont know where to connect it


And i have some kind of multimeter I think, he looks like this Vintage Electronics Radio Shack Micronta Digital Multimeter Model No 22 197 | eBay

But I dont know how to use it

Problem solved!
I think it was a bad original wiring and so the tweeter never played music in +56 years!

I wired the tweeter to the 2 medium connectors and now its sounds exactly the same as the orther speaker
So even the crossover is working great.

The pair is now 100% working

They are beautifully made. I love the routing of the interconnects. Can the Xover be disassembled? I suspect the caps are beyond their use by date.

I dont want do dismantle mine butI found some pictures!

Did you actually change the wiring? If by "medium" you mean "midrange," then you have wired the tweeter to the midrange driver, but surely you realize that can NOT be right??

I protected the tweeter with a 50v 2.2uf cap and it works great! No mediums, only highs

3 ways can be quite simple:
SEAS Kit 503

The simplest circuit I can think of that might work is below in the first two images, but don't take the modelling or values too seriously. Just an idea how it works with 8 ohm drivers.

But your speaker reminded me of the old Tandberg HIFI 15 in the second two images. Similar Celestion and Peerless drivers, but a retro series crossover. I think you should delve. Enjoyed hearing about your speakers. We like vintage.
