DavidDru Posted July 21, 2015 Report Share Posted July 21, 2015 I am going to order what I need for updating the crossovers on my Ones. This is what should be in there, though I have not opened it up yet.Caps:60mfd (2)35mfd (2)6.2mfd (2)3mfd (2)resistors:4ohm (4)3ohm (6)1ohm (2)Looks like I can get most everything in the Dayton 1% caps from Parts Express. The 35uf will need to be 2 put together so I picked a 15uf and a 20uf. Make sense?I am thinking to just go with an NPE for the 60uf to avoid that big cost for a Poly on that. ?Also, there are 12 resistors in there so the Mills start adding up. What is the best alternate? They have the Dayton Precision Audio Grade Low inductive and standard wire wounds. Link to comment Share on other sites More sharing options...
JKent Posted July 22, 2015 Report Share Posted July 22, 2015 IMHOCap selection looks good.Leave the original resistors. They don't go bad. If you must replace them use standard $0.50 wirewounds.-Kent Link to comment Share on other sites More sharing options...
DavidDru Posted July 22, 2015 Author Report Share Posted July 22, 2015 Yea, bagging the resistors might be the way to go. mills would have been near $45!Of course they don't have a single 60 at PE. Link to comment Share on other sites More sharing options...
DavidDru Posted October 23, 2015 Author Report Share Posted October 23, 2015 Any additional thoughts on this from the peanut gang here before I place an order?Binding post upgrade? Link to comment Share on other sites More sharing options...
ra.ra Posted October 23, 2015 Report Share Posted October 23, 2015 Very cool speakers, but just a couple thoughts. Before placing order, I hope you've opened them up to confirm your shopping list, and if possible, maybe you can show pics of original crossover? I like Dayton caps perfectly fine, but count me among those who cannot justify the 50-70% price uptick for the tighter tolerance (1%) white end caps. Also, am unable to comment on the binding posts without a pic or description. The 60uF cap value is a little difficult to find (even with the wide selection from Erse - which is currently showing lotsa "out-of-stock"), so you'll probably have to assemble multiple caps to get close to the target 60 value.

JKent Posted October 25, 2015 Report Share Posted October 25, 2015 I've never been inside Allison: Ones but they're pretty huge so I'd use Madisound "Surplus" 10uF caps for the 60 and 35uF values. You could add a Carli 4.7 to make the 35 (ish). Add a Bennic 0.33 if you wish but it's not needed. The Carli 6.0 is close enough for the 6.2 (or add a Bennic 0.22).Binding posts? My Allison: Fours had perfectly good 5-way binding posts so I don't see the need but if you like fancy binding posts......-Kent Link to comment Share on other sites More sharing options...
DavidDru Posted October 25, 2015 Author Report Share Posted October 25, 2015 Here are my posts. Just simple screw binding posts. Mine must be older than yours? Link to comment Share on other sites More sharing options...
JKent Posted October 25, 2015 Report Share Posted October 25, 2015 hmmmmm. I might replace those. Just check inside and see that they won't be impossible to remove. Also check thickness of the mounting board.btw--I just checked and one pair of Fours I restored had posts like yours.-Kent Link to comment Share on other sites More sharing options...
DavidDru Posted October 25, 2015 Author Report Share Posted October 25, 2015 You think that selector switch is something I could clean with a little deoxit? Link to comment Share on other sites More sharing options...

If so, I'd love to see a pic of the crossover circuitry. I will soon be helping a friend with his Allison Twos, and I cannot seem to locate photos of crossovers for these early models.
