L300 charge coupled crossover questions

[Bama5000lps]

Thanks to member 4313b for posting the L300 schematics in the 4333/S300/L300 equivalent bandbass circuit thread. I have built the passive L300 crossover from the schematic that he posted. The passive crossover works so well that I am now ready to move to the charge-coupled crossover that he posted.

I have two questions about the charged coupled L300 schematic. (I do not have a background in electronics so I am sorry if the questions are simple minded.)

1) Does each charged pair of capacitors require a separate 9V battery?
2) In the midrange portion of the schematic a pair of charged capacitors are 33uF and 39uF. Is there a reason that two 36uF capacitors were not recommended? On every charge coupled schematic I have found the charged capacitors are always in matched pairs.

Thank in advance for any help that you can provide.

1) no (wire the end of the 3meg resistors in the schematic marked +9v together)
2) 33 and 39 uF are standard values (readily available)

Thanks grumpy.
