Hucklecatt Posted June 5, 2020 Report Share Posted June 5, 2020 Before I wrestle with pulling the woofer out to verify, could I ask the group if anyone knows what capacitor is used in this crossover (old metal style) so that I can purchase these and have them on hand when I do pulle everything apart to go in? Many thanks, John Quote Link to comment Share on other sites More sharing options...

Norman Nicolai Posted June 6, 2020 Report Share Posted June 6, 2020 Here's a direct link to the site JKent was referring to: http://baselaudiolab.com/ADVENT_LA_XO.html I had the site saved in my browser since I have changed a number of Advent capacitors. As a matter of fact I'm pretty sure it was JKent who referred me to the site originally! As you will see, Advent changed crossover units during the production run in the OLA, so there is no way of knowing what you need without opening up the cabinet.

Doug G. Posted June 7, 2020 Report Share Posted June 7, 2020 If they are Advents with the metal plate for the crossovers, the caps are most likely 16uF. Those are very early units. Some research shows Advent may have originally used the `16uF/8uF combination in some of the early ones but it is unclear. Regardless, there were only 16uF and 8uF caps used in the original Advents so you would be safe buying some of each. It's not like they are expensive.

Hucklecatt Posted June 8, 2020 Author Report Share Posted June 8, 2020 Thanks Doug and all that is what I will do. I did check that page before posting but the link that is offered for the "Rev 0" values is broken (actually it points back to this page so the information is somewhere on this forum I think). Always one to eat my desert first I did go ahead and refinish the walnut veneer and recover the grille cloth. Quote Link to comment Share on other sites More sharing options...

Doug G. Posted June 14, 2020 Report Share Posted June 14, 2020 Yeah, beautiful! And, you're not alone. I am re-restoring (I originally did it in the mid seventies) an old Hallicafters shortwave radio my late father-in-law had and I got when he passed away in 2015. Even though it needs several parts replaced, particularly the old paper capacitors (it's from the nineteen fifties), and needs to be realigned. I restored the appearance first.
