Lentek S4 crossovers

[stubbs04]

Hi
I'm looking to recap the crossovers on my Lentek S4s.
Trouble is I can't identify the caps or easily make out the values.
See pics attached.
Thanks

say what...? from left to right 4.7, 6.8, 3.3 MFD 100 volt aren't these polyester? don't see why they would be bad.

the coils are much more mysterious....unless you happen to have an inductance bridge.

hope i'm wrong but it looks as though someone used the wrong solder to touch up some of the joints...sad times now i bet.

That's just it I can't tell which are coils and which are caps.

@turk 182
That was what it was like when I opened. Can you explain what looks wrong and is it worth de-soldering and re soldering. Ta.

those yellow blocks are yer caps the white blocks are resistors and the tubular things are coils with ferrite cores.

Just always been advised to change caps. Are polyester much longer lasting than the electrolyte ones?

 

[turk 182]

all the joints that are "whiteish" and dull looking as opposed to shiny and silver are suspect...i've seen that when someone uses a eutectic solder to retouch leaded mixes or much to high a soldering temperature.

You need to find a better 'adviser'.

 

[turk 182]

as to the caps yes poly's are better....as to following conventional wisdom it's a good thing we're not lemmings!

ferrite inductors.....

 

[turk 182]

sure look like ferrite slugs, no?

I'd just like to stress that the yellow film capacitors will not deteriorate over time and consequently do not need replacing.
