Brandyn,

The exact parts are listed in the archieved forum 

I am located in Toronto.. I open them up and pulled the cross overs out, however some of the caps on the crossovers I am unable to find. and I am now sure what caps can be used instead.

I think dillen can give you a kit containing all the caps needed. Otherwise you could give the values needed and we can look for you.

The boards differs from the early mk1 with 82uF to the latest version with 68uF with the very small blue caps.

If your high/low board (pcb 14) contains 82uF capacitors, then so does your board for mids (pcb 15) should.

Like in the above showed mentioned archived topic, you can see that there exists Penta's with boards which are exchanged/swapped/modified without the necessarely knowledge when doing so.

Thanks guys. I have taken the crossovers to an audio guy near me as I just wanted to get them fixed up. One question I have though, is the guy that is looking at them suspects that the tweeters may be blown because the resistors for the Tweeters are burned and the shunt coil is fried as well.

If the tweeters do need to be replaced, does anyone know any good replacements and How can I test the tweeters without a volt meter ?

I had someone rebuild the crossovers for me, and he actually improved them compared to the stock crossovers by doubling the amount connected in series for lower capacitance and higher voltage.

Also, the Tweeter section of the crossover was blown and all the parts needed to be replaced. Whatever happened also took out my tweeters. Login to view image

Let me know what you guys think

Fitting two identical capacitors in series, each of twice the capacitance of the one original they replace will give
a higher voltage rating, that's correct.
But it will not give a lower capacitance (it will be the same as the original) and it will give a doubling
of the (less wanted) series resistance (impedance and/or ESR if you want).
Buying twice the amount of capacitors needed - and at twice the capacitance value (!) will also be very costly.
And why on earth would you do this when 100V bipolar caps are readily available?
I don't get it.

Paralleling electrolytics and foil caps, I feel, is not a great idea either but that's a different story (distortion).

My guess is that this repairer couldn't get the correct values as bipolar electrolytics and therefore
chose this somewhat unusual solution.
It may work in daily use but it's not something, I would recommend.

Well he seemed to know what he was doing and has been in the business for over 30 years restoring vintage audio equipment. The fact is that the boards were badly damaged and I didnt have the expertise on repairing them myself, and to be honest, they sound much better now than they did the last time they were working.

So ill take it as a win.

oh and read the following article.. http://www.coilgun.info/theorycapacitors/capacitors2.htm

"Capacitors connected in series will have a lower total capacitance than any single one in the circuit."
