replace cap in Altec enclosure

[altec9440]

hi,
I'm replacing a cap in speaker enclosure from Altec
I read:
AC
TSI-7844
PA8LP75ACXTFL
8uF-75VAC

I assume It's a 8uF-75VAC cap from a company named TSI.
Red color on each side, no sign, so may be non-polarised aluminium or film ?

I can't find a datasheet but replacing it with a good film cap won't hurt.
Did you measure it?

So am I. May be bought by Vishay...
Not bad for an old piece (manufacturing date 1978) with 7.80uF at 10KHz and 8.6uF at 1KHz. ESR 0,03

Polypropylene film seems a good alternative, just have to find good one for audio with axial leads. Any brand to advise ?

 

[altec9440]

I find only this one Cornell Dubilier. Not sure if it is good for audio ?

Sure.
You could also use 2 of these parallel:

Cheap and good.
