Ed,
Thanks for the info. I was just repeating what Jay (distributor) told me without thinking about it first.
I assume that the covers are to decrease RFI generation from the tubes and shielding from physical damage (being hit, knocked around, etc.)?
So, do the covers not sink ANY heat away from the tubes at all, instead keeping more heat close to the tubes, thereby decreasing operating life?
As far as the pickup/transport, again just repeating what Jay told me. I will have to give him a call again to clear this up.
Thanks and Regards...Mike - Father & Son Audio
