Spud,
I too have to agree with everyone else here about the service Mark offers to his customers. I purchused a Rogue 99 and found out that it was considered a "older" model because of some noise coming from the power supply. I was ready to purchuse some of the Russian nos tubes ($80./set) and Mark mentioned the Magnum upgrade which he even offered to me at a lower price. Needless to say, I went for the Magnum upgrade which would allow it to be fully checked out and updated. I agree with others here that you should go for the Magnum upgrade because you too might have a older 66. Good luck and keep us posted.
