SM152 X-over Caps

[gener8r]

I am going through the crossovers of the SM-152s now that I've braced and added stuffing. The high freq cap is a 3.7uf non-polar Culver, the mid is a 20uf non-polar Culver and the low is a 125uf non-polar. The schematic/tech sheet shows a non polar on the low, but shows the symbol for polarized caps on the mid and high. Can I replace the mid and high non-polar Culvers with a polarized cap such as an Auri or Dayton, ect? Also I cannot find a 3.7uF anywhere, but can find a 3.6, or a 3.9 or a 4.0. Any suggestions? Thanks in advance.

Gener8r, can you pass along the tech sheet for the SM-152s? I cannot find it anywhere on the Web. Thanks in advance.

Give me your e-mail address and I'll forward a pdf. file of the tech sheet to you.

Also, a service manual is available ($14.95) at:

Crossovers use non-polarized capacitors, since they operate with alternating current.

A 3.6uf cap is within tolerance of the 3.7, and you can use it safely.

Can you forward this pdf to me.

Thanks to Geoff727 for the clarification. It is a big help to me, and yes, I'll go with the 3.6!

To Nacon; please give me your email address and I'll send the Tech Sheet to you too.

You can go with 5% tolerance and any number within 10% of published and be better than factory. 3.6 or 3.9 will work fine. Non-polarized all the way :)
