Hi Guys,

I'm not just new to the forum - I'm also a novice in hi-fi and electronics in general.
I'm hoping to get a few basic questions answered here.

My Dad is shipping me his original Monitor Model 5 speakers, from 1978 or 1979.
From what I've seen here, changing all the parts in the crossovers seems like a good starter project for me. (I'm just learning to solder!)

Even though I've seen a bunch of pictures here, I still don't know the answer to a few questions:

1. Is the crossover board a printed circuit, or is it just a piece of material with holes in it for the leads of the components to go through?

2. Do you just twist the leads of the different components together and solder them, or is there more technique involved?

Those two answers should get me started, so thanks to anyone that can answer those.

    Welcome to Club Polk.

    It's printed on the bottom side. The component leads go through holes in the board and are soldered there. You can Google pictures of the boards if you can't wait to see them in person. Don't be twisting stuff, never a good idea.

    Thank you President F1Nut.

    How did you know I couldn't stand the wait?!

    BTW - I searched Google up one side and down the other, looking in vain for even a single image of the non-component side of the circular crossover board.

    Not much to see on the bottom just traces and solder points.

    Thanks for that -- I really just wanted to see what I was getting into, before I got into it! I was thinking that the pieces that made up the crossover connected to each other by having their leads twisted together on the other side of the board. Now I realize they are connected by traces.

    Thanks everyone for welcoming me.

    I don't yet have the speakers in hand, but another question occurred to me.

    I see many here using zip ties to secure the capacitors to the crossover board.
    Can I drill through what looks like copper-plated areas on the board?

    Is that what we're seeing in the image above?

    Those are the holes for mounting the little shunt inductor. You can drill the circuit board, just don't compromise any of the traces while you're doing it

    Thanks for that, but are the traces the coppers areas seen above?

    (meaning I can only drill through the narrow brown lines separating the copper areas?)

    You can drill through the copper traces, but I don't recommend it. Use 3M VHB tape between the board and cap to secure them. Super strong stuff.

    FYI, if you do drill don't breath the fiberglass dust.
