Hi thinkchronicity I'm new to restoring boomboxes, can I ask what these capacitors do (apart from make it sound better) compared to the originals?
Hi there,
disclaimer: pretty new around here too! Here's my understanding so far - well, they are built to a much higher spec, meaning the tolerance is low (measure very close to 10uF, unlike the ones removed), the esr is low (a kind of capacitor 'resistance'), so signal loss to the tweeter is minimized. Also the voltage rating is 5 times the originals. This is unnecessary, but means they are just ticking over at boombox 15v levels, and are nowhere near their maximum limits. Capacitors are complex beasts with many parameters associated with them when you go down the rabbit hole. The way they conduct AC is by conveying the voltage between the plates with an electrostatic field before the signal carries on its journey. I guess this junction where the magic happens can be a source of distortion in cheaper designs - that's what I'm experiencing with the sound anyway.
