@imhififan Wow! What a fine piece of information. Good detective work! Now I've got to decide do I go down the rabbit hole of comparing the sound of capacitors. Mmmmm.......very tempting
Mystery Capacitor and the Tangent RS4 Crossover
I have a pair of
Tangent RS4s whose crossovers I am currently in the midst of trying to
rebuild (Early 80s British 2 way speaker). I used to power them in the 80s with an Adcom GFA1 amp (200
watts/channel which I understand both Bob Carver and Nelson Pass had a
hand in designing back when Adcom was based in New Brunswick, NJ, my old
home town). Apparently, either time or I did a fair amount of damage to
those caps (probably both) and some are hard to id, particularly one
that looks like a piece of pink sugar coated candy with green, white and
violet stripes? I'm working on a schematic for this crossover so I can
get some expert opinion on the project and maybe id the capacitor value by process of elimination. But I am new to this and am
learning as I go. If there is anyone out there interested or who could
lend some assistance I would be happy to share/learn.
I set out to simply replace the caps but am beginning to question the design and wonder if it could not be improved upon. For starters it seems to have a lot of caps for a two way crossover (8 in five styles), plus 2 resistors and 3 coils. Modern designs I have looked at typically have two or three caps for 2 two way crossover.The drivers and cabinets are in good shape and I have always liked this speaker which sports a 200mm Audax bextrene cone woofer and a 19mm KEF t27 dome tweeter, housed in a nicely crafted 42.5 liter walnut veneered mdf cabinet, all of which has held up amazingly well over the yearsI'll try to figure out how to post pictures to this site if anyone is kind enough to offer assistence.
