Messing around with another but of hifi in December. I'm recapping and rewiring a couple of XO's for a pair of Heybrook SB2's. Can anyone tell me who made the green and black caps in the attached photo's and recommend something to replace them.

Thanks

First photo, dunno, but the second photo is of a resistor.

One is a 10uf Cap. Looks like a speaker crossover, so prob non-polar, and the other is a 15 ohm resistor (5% variation)

I'd leave everything alone but the Elcaps. The rest of the parts are good quality and non wearing. Those "filmcap" ones are very expensive.

Thanks again. I always take advice from those with a greater knowledge. That makes my life a little easier. Elcaps are going then.

Advice is as Jez says.

The black capacitor is an Elna Aluminium non polarised bipolar electrolytic 10uF. Its getting on in age and almost all I've tested from old speakers of this type have exhibited high ESR, thee main culprit not being heat/time but oxidised lead out legs developing a micro-porous surface allowing the volatile coatings of the aluminium foils to evaporate over time. New, a 10uF of this type might measure 1 ohm at a few KHz but most I've tested are three to four times this hence in HF sections for crossovers they shift the corner frequency and decrease sensitivity, so it's worth replacing with a new electrolytic of the same value.

The resistor is fine and should be fit for purpose as should be the other cap.
