Hi AllenB, the original red/black Alcaps have drifted up i.e 72uF is reading 124uF and the 60uF is reading 84uF (Fluke 27). These values are a fair bit of tolerance and since I'm really pursuing a modest restoration of Kef B139 B110 T27 Bailey TL that has been stored since 1985 in a corner bedroom. Never played a tune since then. I'm sure U remember 'Dire Straits', 'Australian Crawl' that era. Anyways I'm revisiting them for nostalgic reasons and then moving them on.
So, my effort is here is to research which crossover is best to rebuild, that is either Falcon PCB-5 or Kef DN12.
In the end they will not compete with my JBL 250Ti or Duntechs, no matter what caps I use. To me, in this situation, the cost of Mcaps or Elcaps electros are bit overhyped and overpriced (for me anyways) but I want them to go a good home. So, a half decent recap using inexpensive NP electros or other hand, the film/foil caps have longevity.
The front and back panels are 25mm particle board with front and back panels able to be removed to load the transmission line with suitable fill. I never did get that anywhere near right. So plenty to do besides the crossover. The cabinets were custom made by Southport HiFi here on the Gold Coast. I did the final fitting out and sealing of panels. These panels fixings are severely over engineered which what I was like back in the day... Here is a pic, sorry about the quality, but its hard to get to ATM.
