Converting my cornwall B xover to B2

[pythagore]

I have a pair of cornwall 1 that is currently using the B xover, I would like to convert the xover to B2.

Per the difference between the B and B2 schematics, I only need to do the following:

- Woofer circuit - add a 20uF in parallel.  No Change to Polarity +/-

- Mid circuit- replace the 4uF with 3uF. Change polarity to -/+

- Tweeter circuit -  add a 245uH in parallel. Change polarity to -/+

 

My only issue is that I can't find a 245uH inductor in Canada, can a 14AWG 0.24mH (240uH) be used as a replacement?

Thanks,

Please, delete this topic; I have found the answer in this old topic.

I have changed Cornwall 1 xover from B to B2, I am glad that I did. B2 provides substantial, very noticeable sonic improvement over B.
