Hello Vesa, yes, it seems it's no longer possible to show pictures here, but i think i have your mail, i can show you some pics there?
If you can't show pics this diy-forum isn't much to use anymore. Undecided.

Strange. All pictures have gone broken. At least for me...

Hello, after having my CII,s stored for about 5 years i was recently rebuild them a bit, a new two-way x-over is replacing my old for midrange and tweeter.
The new crossover is originally made for another speaker but the construction allows to use it with pretty good results also with other drivers.
Driver-impedance is not as critical here, most x-over problems usually occurs in x-over points, with phaseproblems and peaks or dips in the frequency curve as a result, with this unit the transition is smooth, i have done adjustments in level with an L-pad because midrange was to loud.

Don't do anything to the coils.  Most likely they will be just fine.  If you want to do the capacitors, do them EXACTLY to the originals, including the bundling to get the right values.  Do not combine into a single capacitor, do it just like Peter Snell did.  If you do that, you should get very good results.

Sorry I  meant to thank you both for the input. I will definitely build new crossovers and keep the originals, if I do this project at all. However, I am not sure how to duplicate the coil windings, since I understand they are usually customized to meet the reference pair at the factory. At least I think this is the case.

I have owned many pairs of Type As over the years and now have a superb pair. The tweeter, if memory serves, is different than I remember from my first set of Type As, though I am pretty certain they are original. I have read that there may be two early versions, the Type A-I and the Type A-Original. I never knew this before. Is this true, and if so what is the difference? My pair is serial  numbers 243/244. See oics. Separately fused tweeter/mid/woofer. the round plate surrounding the tweeter is white, and a dispersion bar across it diagonally. There are no felt pads near the tweeters but shoukd it have them? they may have been removed by previous owner. It does have the insulation pads hanging inside the speaker grilles.

How can I tell which model I have, assuming there really is such thing as a "Type A-Original"?

Thanks for any thoughts!

The meaning with the contact to increase or keep the response flat. In some inviroments, some persons have more curtains, carpets and furniture than the most, who will eat the treble. Here you can use the contact to increase the tweeter level. It could be possible, that it works from the crossover point and all the way up. It was only a wild guess from me. Grin If you look at the regulator in the speakers from Kevin Voecks, you will see, that from the crossover point (2700)- (K3,E3 and J3), there are some area from 2700 to 4000hz, the regulator do not work, but from there and the rest of the way up. That is because the tweeter cannot reach the woofer properly. It looses some level here. It's the tweeter it self, who has that response on it's curve. In the later Ai and A2, Peter Snell did not use that feature. That is because, that the speakers has much better dispersion and energy than the first A. Here you have to have a little toe in, you don't need that with the Ai and A2 or A3 for that sake.  Smiley

Due error on the page, you cannot see the pics you posted. But the original A has a tweeter with a some kind of a grate, as the older tweeter from Seas from the seventies, in front of the dome. The Ai, has the tweeter from Audax with the brezzel in front of the tweeter to increase the dispersion. When the Ai got a new midrange, it changes the type to A2.  Smiley
