It certainly is an honor to have my first query answered by the big man himself, Wow! Thanks Harv.
I have another question: I want to use a d130 to replace the two 12 Jensens in my 1965 silvertone 1484 piggy back amp. (It has two 6L6's in a push pull circuit, but I don't know how many ohms the amp is looking for) I don't know if I should use a 16 ohm or a 8 ohm speaker. The problem is that the amp is too loud for my requirements so i was thinking of using a 16 OHM speaker to soak up some of the power. I read some other missives about the cab size and sound deadening material which I will also incorporate but I still need to get the amp up to "3" or "4 " to get the full amp character.
