[HAM] Impedance variations in Ham/Suz drivers

[Dave Bishop]

Impedance varies with the frequency produced.  What impedance do you get 
when you put a 1Khz siganl through the driver?

I may be wrong, but I don't think "B3 Guys" or its owner(s) is a member on 
this list.  I try to solicit a bid from one of the professional Hammond 
techs who have established their business reputation on these forums, 
because I'm sure they will go the extra mile to keep that reputation 
pristine.  If I'd received your driver, I'd be on the phone immediately.

I don't know about shipping charges:  how far are you from Nashville, and 
how quickly did you need the driver?  Was the shipping more than you were 
quoted?

Your report is the first I've heard about buzzing in factory fresh samples, 
but rough handling during shipment could have had some effect.  Glad you got 
it working again on your own.  How do you like the sound?  Some have 
reported that its a bit brighter than a stock V21.

Regards,

Dave Bishop
