Nice find, I hope everything works out.
But, I have to agree with Nexus. The TL cabinet was tailored to the original driver specs.
GOOD LUCK!
So that's where my yang is, I knew it, I don't like the cold weather there either. I've seen a few old ESS woofers for sale, same look and design as the 690-0007 but not the right ones so far. I'm just going to make sure not to do any mods to the cab I can't undo if I don't put originals in.
The Mills and the Dayton sand-cast are both wire-wound. The Mills' are a higher end product - one may not be able to hear the difference between the two, but anyone can appreciate the durability of the better product. I used them in a crossover project for their physical dimensions as i couldn't get sand-cast the same size as the originals, but I doubt that they made an audible difference.Oh yeah, Seattle, I was thinking Idaho, the Dakotas, my ADD type of reading is annoying. I've always wanted to check out that rainforest there on the coast. I've been looking at resistors, what's so fancy-pants about the Mills brand? Is there still a wound wire going through it? I've never ordered or replaced a resistor btw. I think I will go to the Fry's Electronics here first before I order, they will probably have what I need there. I need to call ESS about the woofers, they have called here twice now. I have too many projects going.
For the love of all that is holy, DO NOT make the same mistake as the manufacturer or any previous owners did and glue anything that may need to be removed in the future. The internet makes readily available all sorts of cool, DRY ways to cushion/seal things together.I have the screws out but the white putty sealant used around the speaker cage is a little more than putty strength, it might be difficult to get them out but I'm going to work on it. These things are practically glued in but I'll get them out. What was the sealant like on the originals, it might be a clue also. But, doesn't matter, I'll get one of these out so we can see. imo the cone has an Advent look to it.
You can parallel multiple capacitors together to get the desired value. For example, you could twist the leads of a 50 uF cap with the leads of a 1.5 uF cap to get the desired value of 51.5 uF. The linked caps are electrolytic. Poly caps are considerably bigger and more expensive - in the case of the large cap ( 75 uF - 68 uF+ 6.8 uF) in the woofer leg, a poly cap would be money wasted as the lower frequencies don't benefit from poly-caps.I'm at the AMTs again and have the crossover out on one. I have a confession, this is my first cap job and I don't know what to order.
One says 33uf-75VNP
... 51.5uf-75vnp
and 75mfd 75vnp
I go to a site like PartsExpress but I don't get the exact numbers, do they translate to something else? I took pics of everything so I know what went where. I really need some guidance in exactly what to order, it freezes me up looking at all that's available at PartsExpress.
I was recommended these from the associated co. The outside diameter of the hole is 10.5" on the cabs. I still haven't called ESS but I will. Everybody is trying to make a sale so it's hard to know what will work best.

Now I see the fuse holders I ordered don't quite fit in the mounting hole, have to look for some that fit or drill out a little which I'd rather not do.
The "eurocard" was actually an easier way to deal with the big, fat caps than attaching them to the original PC board. You had to be able to solder to a PC board either way. The difficulty with the eurocard was the patience needed to lay it out. Then it's just a matter or running wires from cap circuit on the eurocard to it's respective capacitor holes on the original PC board.Good lord who ARE you! You know what that looks like to me? ...dangerous! I'm going to study this more, I'd love to feel like I know what's going on, to understand it better. I was just happy to get the caps out with my iron, "Wow, look at me!" When I get the new caps in and they work, that will be a good thing. The guy I bought them from said he couldn't get a sound out of either one of them. I do have giant centipedes in containers in the house, captive born. I started catching bugs when I was 2, still a kid 5 decades later. But I also sell that stuff to a pet store and on the internet, sometimes.
