Re: [PSUBS-MAILIST] Ballast Questions

["Brian Cox" <ojaivalleybeefarm@dslextreme.com>]

Thanks Dan and Carsten,  

 Carsten, I have a friend who is over in Germany right now with his new German wife !  He's meeting her parents for the first time,  I gave them your web site so maybe you will have some visitors !  

Thanks for the info,  that must be a tricky balancing act having the ballast on either end of the sub.  I would like to see that compensating chain drive mechanism, that is very interesting,  it seems like that would be very hard to control !

Brian
